Given numbers are 637, 228, 218, 531

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

Apply this formula for all numbers.

Step1:

LCM(637, 228) = 145236

GCD(637, 228) = ( 637 x 228 ) / 145236

= 637 / 228

= 637

Step2:

LCM(1, 218) = 218

GCD(1, 218) = ( 1 x 218 ) / 218

= 1 / 218

= 1

Step3:

LCM(1, 531) = 531

GCD(1, 531) = ( 1 x 531 ) / 531

= 1 / 531

= 1

So, Greatest Common Divisor of 637, 228, 218, 531 is 1
