GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(798, 402) = 53466
GCD(798, 402) = ( 798 x 402 ) / 53466
= 798 / 402
= 798
Step2:
LCM(6, 657) = 1314
GCD(6, 657) = ( 6 x 657 ) / 1314
= 6 / 657
= 6
Step3:
LCM(3, 172) = 516
GCD(3, 172) = ( 3 x 172 ) / 516
= 3 / 172
= 3
So, Greatest Common Divisor of 798, 402, 657, 172 is 1
