Given numbers are 640, 418, 310, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(640, 418) = 133760
GCD(640, 418) = ( 640 x 418 ) / 133760
= 640 / 418
= 640
Step2:
LCM(2, 310) = 310
GCD(2, 310) = ( 2 x 310 ) / 310
= 2 / 310
= 2
Step3:
LCM(2, 771) = 1542
GCD(2, 771) = ( 2 x 771 ) / 1542
= 2 / 771
= 2
So, Greatest Common Divisor of 640, 418, 310, 771 is 1
