Given numbers are 667, 530, 397, 688
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(667, 530) = 353510
GCD(667, 530) = ( 667 x 530 ) / 353510
= 667 / 530
= 667
Step2:
LCM(1, 397) = 397
GCD(1, 397) = ( 1 x 397 ) / 397
= 1 / 397
= 1
Step3:
LCM(1, 688) = 688
GCD(1, 688) = ( 1 x 688 ) / 688
= 1 / 688
= 1
So, Greatest Common Divisor of 667, 530, 397, 688 is 1
