Given numbers are 917, 140, 487, 451
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(917, 140) = 18340
GCD(917, 140) = ( 917 x 140 ) / 18340
= 917 / 140
= 917
Step2:
LCM(7, 487) = 3409
GCD(7, 487) = ( 7 x 487 ) / 3409
= 7 / 487
= 7
Step3:
LCM(1, 451) = 451
GCD(1, 451) = ( 1 x 451 ) / 451
= 1 / 451
= 1
So, Greatest Common Divisor of 917, 140, 487, 451 is 1
