GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 962) = 306878
GCD(638, 962) = ( 638 x 962 ) / 306878
= 638 / 962
= 638
Step2:
LCM(2, 871) = 1742
GCD(2, 871) = ( 2 x 871 ) / 1742
= 2 / 871
= 2
Step3:
LCM(1, 492) = 492
GCD(1, 492) = ( 1 x 492 ) / 492
= 1 / 492
= 1
So, Greatest Common Divisor of 638, 962, 871, 492 is 1
