GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(639, 625) = 399375
GCD(639, 625) = ( 639 x 625 ) / 399375
= 639 / 625
= 639
Step2:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
Step3:
LCM(1, 346) = 346
GCD(1, 346) = ( 1 x 346 ) / 346
= 1 / 346
= 1
So, Greatest Common Divisor of 639, 625, 688, 346 is 1
