Given numbers are 493, 640, 765, 279
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(493, 640) = 315520
GCD(493, 640) = ( 493 x 640 ) / 315520
= 493 / 640
= 493
Step2:
LCM(1, 765) = 765
GCD(1, 765) = ( 1 x 765 ) / 765
= 1 / 765
= 1
Step3:
LCM(1, 279) = 279
GCD(1, 279) = ( 1 x 279 ) / 279
= 1 / 279
= 1
So, Greatest Common Divisor of 493, 640, 765, 279 is 1
