Given numbers are 638, 336, 423, 304
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(638, 336) = 107184
GCD(638, 336) = ( 638 x 336 ) / 107184
= 638 / 336
= 638
Step2:
LCM(2, 423) = 846
GCD(2, 423) = ( 2 x 423 ) / 846
= 2 / 423
= 2
Step3:
LCM(1, 304) = 304
GCD(1, 304) = ( 1 x 304 ) / 304
= 1 / 304
= 1
So, Greatest Common Divisor of 638, 336, 423, 304 is 1
