GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 960) = 127680
GCD(798, 960) = ( 798 x 960 ) / 127680
= 798 / 960
= 798
Step2:
LCM(6, 639) = 1278
GCD(6, 639) = ( 6 x 639 ) / 1278
= 6 / 639
= 6
Step3:
LCM(3, 197) = 591
GCD(3, 197) = ( 3 x 197 ) / 591
= 3 / 197
= 3
So, Greatest Common Divisor of 798, 960, 639, 197 is 1
