GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(980, 511) = 71540
GCD(980, 511) = ( 980 x 511 ) / 71540
= 980 / 511
= 980
Step2:
LCM(7, 462) = 462
GCD(7, 462) = ( 7 x 462 ) / 462
= 7 / 462
= 7
Step3:
LCM(7, 798) = 798
GCD(7, 798) = ( 7 x 798 ) / 798
= 7 / 798
= 7
So, Greatest Common Divisor of 980, 511, 462, 798 is 7
