Given numbers are 681, 387, 614, 630
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(681, 387) = 87849
GCD(681, 387) = ( 681 x 387 ) / 87849
= 681 / 387
= 681
Step2:
LCM(3, 614) = 1842
GCD(3, 614) = ( 3 x 614 ) / 1842
= 3 / 614
= 3
Step3:
LCM(1, 630) = 630
GCD(1, 630) = ( 1 x 630 ) / 630
= 1 / 630
= 1
So, Greatest Common Divisor of 681, 387, 614, 630 is 1
