Step(1): Factorize the numbers into their prime factors.$$ 21 = 3 \times 7 = 3^{1} \times 7^{1} $$ $$ 28 = 2 \times 2 \times 7 = 2^{2} \times 7^{1} $$ $$ 32 = 2 \times 2 \times 2 \times 2 \times 2 = 2^{5} $$ Step(2): Collect all the distinct factors with their maximum available power.$$ = 2^{5}, \ 3^{1}, \ 7^{1} $$ Step(3): Multiply the collected factors.$$ = 2^{5} \times 3^{1} \times 7^{1} $$ $$ = 32 \times 3 \times 7 = 672 $$
Step(1): Factorize the numbers into their prime factors.$$ 7 = 7^{1} $$ $$ 11 = 11^{1} $$ $$ 13 = 13^{1} $$ $$ 17 = 17^{1} $$Step(2): Collect all the distinct factors with their maximum available power.$$ = 7^{1}, \ 11^{1}, \ 13^{1}, \ and \ 17^{1} $$ Step(3): Multiply the collected factors.$$ = 7 \times 11 \times 13 \times 17 = 17017 $$
