Given numbers are 765, 391, 570, 426
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(765, 391) = 17595
GCD(765, 391) = ( 765 x 391 ) / 17595
= 765 / 391
= 765
Step2:
LCM(17, 570) = 9690
GCD(17, 570) = ( 17 x 570 ) / 9690
= 17 / 570
= 17
Step3:
LCM(1, 426) = 426
GCD(1, 426) = ( 1 x 426 ) / 426
= 1 / 426
= 1
So, Greatest Common Divisor of 765, 391, 570, 426 is 1
