GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(664, 792) = 65736
GCD(664, 792) = ( 664 x 792 ) / 65736
= 664 / 792
= 664
Step2:
LCM(8, 625) = 5000
GCD(8, 625) = ( 8 x 625 ) / 5000
= 8 / 625
= 8
Step3:
LCM(1, 645) = 645
GCD(1, 645) = ( 1 x 645 ) / 645
= 1 / 645
= 1
So, Greatest Common Divisor of 664, 792, 625, 645 is 1
