GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(691, 387) = 267417
GCD(691, 387) = ( 691 x 387 ) / 267417
= 691 / 387
= 691
Step2:
LCM(1, 964) = 964
GCD(1, 964) = ( 1 x 964 ) / 964
= 1 / 964
= 1
Step3:
LCM(1, 608) = 608
GCD(1, 608) = ( 1 x 608 ) / 608
= 1 / 608
= 1
So, Greatest Common Divisor of 691, 387, 964, 608 is 1
