Given numbers are 390, 957, 887, 680
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(390, 957) = 124410
GCD(390, 957) = ( 390 x 957 ) / 124410
= 390 / 957
= 390
Step2:
LCM(3, 887) = 2661
GCD(3, 887) = ( 3 x 887 ) / 2661
= 3 / 887
= 3
Step3:
LCM(1, 680) = 680
GCD(1, 680) = ( 1 x 680 ) / 680
= 1 / 680
= 1
So, Greatest Common Divisor of 390, 957, 887, 680 is 1
