Given numbers are 430, 658, 625, 745
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 658) = 141470
GCD(430, 658) = ( 430 x 658 ) / 141470
= 430 / 658
= 430
Step2:
LCM(2, 625) = 1250
GCD(2, 625) = ( 2 x 625 ) / 1250
= 2 / 625
= 2
Step3:
LCM(1, 745) = 745
GCD(1, 745) = ( 1 x 745 ) / 745
= 1 / 745
= 1
So, Greatest Common Divisor of 430, 658, 625, 745 is 1
