Given numbers are 454, 139, 251, 419
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(454, 139) = 63106
GCD(454, 139) = ( 454 x 139 ) / 63106
= 454 / 139
= 454
Step2:
LCM(1, 251) = 251
GCD(1, 251) = ( 1 x 251 ) / 251
= 1 / 251
= 1
Step3:
LCM(1, 419) = 419
GCD(1, 419) = ( 1 x 419 ) / 419
= 1 / 419
= 1
So, Greatest Common Divisor of 454, 139, 251, 419 is 1
