GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(246, 276) = 11316
GCD(246, 276) = ( 246 x 276 ) / 11316
= 246 / 276
= 246
Step2:
LCM(6, 686) = 2058
GCD(6, 686) = ( 6 x 686 ) / 2058
= 6 / 686
= 6
Step3:
LCM(2, 640) = 640
GCD(2, 640) = ( 2 x 640 ) / 640
= 2 / 640
= 2
So, Greatest Common Divisor of 246, 276, 686, 640 is 2
