Given numbers are 375, 555, 747, 638

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(375, 555) = 13875

GCD(375, 555) = ( 375 x 555 ) / 13875

= 375 / 555

= 375

Step2:

LCM(15, 747) = 3735

GCD(15, 747) = ( 15 x 747 ) / 3735

= 15 / 747

= 15

Step3:

LCM(3, 638) = 1914

GCD(3, 638) = ( 3 x 638 ) / 1914

= 3 / 638

= 3

So, Greatest Common Divisor of 375, 555, 747, 638 is 1
