Given numbers are 423, 651, 637, 159
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(423, 651) = 91791
GCD(423, 651) = ( 423 x 651 ) / 91791
= 423 / 651
= 423
Step2:
LCM(3, 637) = 1911
GCD(3, 637) = ( 3 x 637 ) / 1911
= 3 / 637
= 3
Step3:
LCM(1, 159) = 159
GCD(1, 159) = ( 1 x 159 ) / 159
= 1 / 159
= 1
So, Greatest Common Divisor of 423, 651, 637, 159 is 1
