Given numbers are 626, 452, 645, 130
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(626, 452) = 141476
GCD(626, 452) = ( 626 x 452 ) / 141476
= 626 / 452
= 626
Step2:
LCM(2, 645) = 1290
GCD(2, 645) = ( 2 x 645 ) / 1290
= 2 / 645
= 2
Step3:
LCM(1, 130) = 130
GCD(1, 130) = ( 1 x 130 ) / 130
= 1 / 130
= 1
So, Greatest Common Divisor of 626, 452, 645, 130 is 1
