Given numbers are 159, 638, 100, 122
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(159, 638) = 101442
GCD(159, 638) = ( 159 x 638 ) / 101442
= 159 / 638
= 159
Step2:
LCM(1, 100) = 100
GCD(1, 100) = ( 1 x 100 ) / 100
= 1 / 100
= 1
Step3:
LCM(1, 122) = 122
GCD(1, 122) = ( 1 x 122 ) / 122
= 1 / 122
= 1
So, Greatest Common Divisor of 159, 638, 100, 122 is 1
