Given numbers are 660, 640, 248, 102
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(660, 640) = 21120
GCD(660, 640) = ( 660 x 640 ) / 21120
= 660 / 640
= 660
Step2:
LCM(20, 248) = 1240
GCD(20, 248) = ( 20 x 248 ) / 1240
= 20 / 248
= 20
Step3:
LCM(4, 102) = 204
GCD(4, 102) = ( 4 x 102 ) / 204
= 4 / 102
= 4
So, Greatest Common Divisor of 660, 640, 248, 102 is 2
