Given numbers are 637, 218, 133, 197
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(637, 218) = 138866
GCD(637, 218) = ( 637 x 218 ) / 138866
= 637 / 218
= 637
Step2:
LCM(1, 133) = 133
GCD(1, 133) = ( 1 x 133 ) / 133
= 1 / 133
= 1
Step3:
LCM(1, 197) = 197
GCD(1, 197) = ( 1 x 197 ) / 197
= 1 / 197
= 1
So, Greatest Common Divisor of 637, 218, 133, 197 is 1
