Given numbers are 638, 748, 487, 200

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

Apply this formula for all numbers.

Step1:

LCM(638, 748) = 21692

GCD(638, 748) = ( 638 x 748 ) / 21692

= 638 / 748

= 638

Step2:

LCM(22, 487) = 10714

GCD(22, 487) = ( 22 x 487 ) / 10714

= 22 / 487

= 22

Step3:

LCM(1, 200) = 200

GCD(1, 200) = ( 1 x 200 ) / 200

= 1 / 200

= 1

So, Greatest Common Divisor of 638, 748, 487, 200 is 1
