Given numbers are 315, 689, 681, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(315, 689) = 217035
GCD(315, 689) = ( 315 x 689 ) / 217035
= 315 / 689
= 315
Step2:
LCM(1, 681) = 681
GCD(1, 681) = ( 1 x 681 ) / 681
= 1 / 681
= 1
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 315, 689, 681, 530 is 1
