Given numbers are 386, 440, 657, 860
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 440) = 84920
GCD(386, 440) = ( 386 x 440 ) / 84920
= 386 / 440
= 386
Step2:
LCM(2, 657) = 1314
GCD(2, 657) = ( 2 x 657 ) / 1314
= 2 / 657
= 2
Step3:
LCM(1, 860) = 860
GCD(1, 860) = ( 1 x 860 ) / 860
= 1 / 860
= 1
So, Greatest Common Divisor of 386, 440, 657, 860 is 1
