Given numbers are 251, 191, 654, 120
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 191) = 47941
GCD(251, 191) = ( 251 x 191 ) / 47941
= 251 / 191
= 251
Step2:
LCM(1, 654) = 654
GCD(1, 654) = ( 1 x 654 ) / 654
= 1 / 654
= 1
Step3:
LCM(1, 120) = 120
GCD(1, 120) = ( 1 x 120 ) / 120
= 1 / 120
= 1
So, Greatest Common Divisor of 251, 191, 654, 120 is 1
