Given numbers are 631, 742, 391, 104
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(631, 742) = 468202
GCD(631, 742) = ( 631 x 742 ) / 468202
= 631 / 742
= 631
Step2:
LCM(1, 391) = 391
GCD(1, 391) = ( 1 x 391 ) / 391
= 1 / 391
= 1
Step3:
LCM(1, 104) = 104
GCD(1, 104) = ( 1 x 104 ) / 104
= 1 / 104
= 1
So, Greatest Common Divisor of 631, 742, 391, 104 is 1
