Given numbers are 251, 655, 742, 453
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(251, 655) = 164405
GCD(251, 655) = ( 251 x 655 ) / 164405
= 251 / 655
= 251
Step2:
LCM(1, 742) = 742
GCD(1, 742) = ( 1 x 742 ) / 742
= 1 / 742
= 1
Step3:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
So, Greatest Common Divisor of 251, 655, 742, 453 is 1
