Given numbers are 817, 287, 453, 137
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(817, 287) = 234479
GCD(817, 287) = ( 817 x 287 ) / 234479
= 817 / 287
= 817
Step2:
LCM(1, 453) = 453
GCD(1, 453) = ( 1 x 453 ) / 453
= 1 / 453
= 1
Step3:
LCM(1, 137) = 137
GCD(1, 137) = ( 1 x 137 ) / 137
= 1 / 137
= 1
So, Greatest Common Divisor of 817, 287, 453, 137 is 1
