Given numbers are 386, 284, 815, 646
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(386, 284) = 54812
GCD(386, 284) = ( 386 x 284 ) / 54812
= 386 / 284
= 386
Step2:
LCM(2, 815) = 1630
GCD(2, 815) = ( 2 x 815 ) / 1630
= 2 / 815
= 2
Step3:
LCM(1, 646) = 646
GCD(1, 646) = ( 1 x 646 ) / 646
= 1 / 646
= 1
So, Greatest Common Divisor of 386, 284, 815, 646 is 1
