We know that 128 is an even number, so it&#8217;s divisible by 2 (the smallest prime number).<\/p>\n\n\n\n<p>128\u00f72=64128 \u00f7 2 = 64128\u00f72=64<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 2: Continue factoring 64<\/h3>\n\n\n\n<p>Now we have 64. Since 64 is also even, we can divide it by 2.<\/p>\n\n\n\n<p>64\u00f72=3264 \u00f7 2 = 3264\u00f72=32<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 3: Continue factoring 32<\/h3>\n\n\n\n<p>We continue with 32, which is also even. Dividing by 2 again gives us:<\/p>\n\n\n\n<p>32\u00f72=1632 \u00f7 2 = 1632\u00f72=16<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 4: Continue factoring 16<\/h3>\n\n\n\n<p>Now we have 16, and since it&#8217;s even, we divide it by 2 again:<\/p>\n\n\n\n<p>16\u00f72=816 \u00f7 2 = 816\u00f72=8<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 5: Continue factoring 8<\/h3>\n\n\n\n<p>We keep going with 8, which is also divisible by 2:<\/p>\n\n\n\n<p>8\u00f72=48 \u00f7 2 = 48\u00f72=4<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 6: Continue factoring 4<\/h3>\n\n\n\n<p>We now have 4, and since it&#8217;s even, we divide by 2 once again:<\/p>\n\n\n\n<p>4\u00f72=24 \u00f7 2 = 24\u00f72=2<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 7: Final factor<\/h3>\n\n\n\n<p>At this point, we are left with 2, which is a prime number, and we stop here.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">Step 8: Prime factorization of 128<\/h3>\n\n\n\n<p>The factor tree is now complete.
