GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(658, 538) = 177002
GCD(658, 538) = ( 658 x 538 ) / 177002
= 658 / 538
= 658
Step2:
LCM(2, 239) = 478
GCD(2, 239) = ( 2 x 239 ) / 478
= 2 / 239
= 2
Step3:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
So, Greatest Common Divisor of 658, 538, 239, 828 is 1
