GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(782, 642) = 251022
GCD(782, 642) = ( 782 x 642 ) / 251022
= 782 / 642
= 782
Step2:
LCM(2, 308) = 308
GCD(2, 308) = ( 2 x 308 ) / 308
= 2 / 308
= 2
Step3:
LCM(2, 624) = 624
GCD(2, 624) = ( 2 x 624 ) / 624
= 2 / 624
= 2
So, Greatest Common Divisor of 782, 642, 308, 624 is 2
