Question

if hcf (516 ,42) =6 find the lcm (516 ,42).

Answer 1

HCF * LCM= PRODUCT OF TWO NUMBER

6 * LCM = 516 * 42

LCM = 516*42/6

LCM = 516 * 7

LCM = 3612

THEREFORE = LCM = 3612

HOPE FULL , I HELP YOU

Answer 2

Answer:

METHOD 1 : HCF X LCM = PRODUCT OF TWO NUMBERS

6 X LCM = 516 X 42

LCM = 516 X 42 /6

LCM = 516 X 7

LCM = 3612

METHD 2:

516 = 2 X2 X3 X43

42 = 2 X 3X 7

LCM = 2 X 2X 3X 7 X 43  = 3612

LCM = 3612
