GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(212, 530) = 1060
GCD(212, 530) = ( 212 x 530 ) / 1060
= 212 / 530
= 212
Step2:
LCM(106, 816) = 43248
GCD(106, 816) = ( 106 x 816 ) / 43248
= 106 / 816
= 106
Step3:
LCM(2, 638) = 638
GCD(2, 638) = ( 2 x 638 ) / 638
= 2 / 638
= 2
So, Greatest Common Divisor of 212, 530, 816, 638 is 2
