What is the least common multiple of #{7, 18, 21, 48}#?

Answer 1

Skylar Adams

Least Common Multiple is #1008#

Prime factors of #7# are #7#

Prime factors of #18# are #2xx3xx3#

Prime factors of #21# are #3xx7#

Prime factors of #48# are #2xx2xx2xx2xx3#

Here #2# occurs maximum of four times, #3# occurs maximum of two times and #7# occurs just once.

Hence Least Common Multiple is #2xx2xx2xx2xx3xx3xx7=1008#
