Given numbers are 786, 638, 320, 355
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(786, 638) = 250734
GCD(786, 638) = ( 786 x 638 ) / 250734
= 786 / 638
= 786
Step2:
LCM(2, 320) = 320
GCD(2, 320) = ( 2 x 320 ) / 320
= 2 / 320
= 2
Step3:
LCM(2, 355) = 710
GCD(2, 355) = ( 2 x 355 ) / 710
= 2 / 355
= 2
So, Greatest Common Divisor of 786, 638, 320, 355 is 1
