Given numbers are 638, 613, 368, 148
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 613) = 391094
GCD(638, 613) = ( 638 x 613 ) / 391094
= 638 / 613
= 638
Step2:
LCM(1, 368) = 368
GCD(1, 368) = ( 1 x 368 ) / 368
= 1 / 368
= 1
Step3:
LCM(1, 148) = 148
GCD(1, 148) = ( 1 x 148 ) / 148
= 1 / 148
= 1
So, Greatest Common Divisor of 638, 613, 368, 148 is 1
