Given numbers are 671, 687, 251, 891
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(671, 687) = 460977
GCD(671, 687) = ( 671 x 687 ) / 460977
= 671 / 687
= 671
Step2:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
Step3:
LCM(1, 891) = 891
GCD(1, 891) = ( 1 x 891 ) / 891
= 1 / 891
= 1
So, Greatest Common Divisor of 671, 687, 251, 891 is 1
