Given numbers are 391, 542, 326, 637
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(391, 542) = 211922
GCD(391, 542) = ( 391 x 542 ) / 211922
= 391 / 542
= 391
Step2:
LCM(1, 326) = 326
GCD(1, 326) = ( 1 x 326 ) / 326
= 1 / 326
= 1
Step3:
LCM(1, 637) = 637
GCD(1, 637) = ( 1 x 637 ) / 637
= 1 / 637
= 1
So, Greatest Common Divisor of 391, 542, 326, 637 is 1
