Given numbers are 390, 681, 956, 697
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 681) = 88530
GCD(390, 681) = ( 390 x 681 ) / 88530
= 390 / 681
= 390
Step2:
LCM(3, 956) = 2868
GCD(3, 956) = ( 3 x 956 ) / 2868
= 3 / 956
= 3
Step3:
LCM(1, 697) = 697
GCD(1, 697) = ( 1 x 697 ) / 697
= 1 / 697
= 1
So, Greatest Common Divisor of 390, 681, 956, 697 is 1
