GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(643, 688) = 442384
GCD(643, 688) = ( 643 x 688 ) / 442384
= 643 / 688
= 643
Step2:
LCM(1, 925) = 925
GCD(1, 925) = ( 1 x 925 ) / 925
= 1 / 925
= 1
Step3:
LCM(1, 717) = 717
GCD(1, 717) = ( 1 x 717 ) / 717
= 1 / 717
= 1
So, Greatest Common Divisor of 643, 688, 925, 717 is 1
