Given numbers are 881, 159, 517, 644
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(881, 159) = 140079
GCD(881, 159) = ( 881 x 159 ) / 140079
= 881 / 159
= 881
Step2:
LCM(1, 517) = 517
GCD(1, 517) = ( 1 x 517 ) / 517
= 1 / 517
= 1
Step3:
LCM(1, 644) = 644
GCD(1, 644) = ( 1 x 644 ) / 644
= 1 / 644
= 1
So, Greatest Common Divisor of 881, 159, 517, 644 is 1
