GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 716) = 229836
GCD(642, 716) = ( 642 x 716 ) / 229836
= 642 / 716
= 642
Step2:
LCM(2, 487) = 974
GCD(2, 487) = ( 2 x 487 ) / 974
= 2 / 487
= 2
Step3:
LCM(1, 112) = 112
GCD(1, 112) = ( 1 x 112 ) / 112
= 1 / 112
= 1
So, Greatest Common Divisor of 642, 716, 487, 112 is 1
