Question

Find the lcm of 352,472,500 and 650
by finding their HCf​

Answer 1

Answer:

Solution by Greatest Common Factor

LCM(352, 472, 500, 650) =

LCM(LCM(LCM(352, 472), 500), 650)

Working from the innermost parentheses outward:

LCM(352,472) = (352 × 472) / GCF(352,472)

= (352 × 472) / 8

= 166144 / 8

= 20768

LCM(20768,500) = (20768 × 500) / GCF(20768,500)

= (20768 × 500) / 4

= 10384000 / 4

= 2596000

LCM(2596000,650) = (2596000 × 650) / GCF(2596000,650)

= (2596000 × 650) / 50

= 1687400000 / 50

= 33748000

Therefore,

LCM(352, 472, 500, 650) = 33,748,000
