GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(642, 798) = 85386
GCD(642, 798) = ( 642 x 798 ) / 85386
= 642 / 798
= 642
Step2:
LCM(6, 519) = 1038
GCD(6, 519) = ( 6 x 519 ) / 1038
= 6 / 519
= 6
Step3:
LCM(3, 767) = 2301
GCD(3, 767) = ( 3 x 767 ) / 2301
= 3 / 767
= 3
So, Greatest Common Divisor of 642, 798, 519, 767 is 1
