Given numbers are 287, 478, 267, 561
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 478) = 137186
GCD(287, 478) = ( 287 x 478 ) / 137186
= 287 / 478
= 287
Step2:
LCM(1, 267) = 267
GCD(1, 267) = ( 1 x 267 ) / 267
= 1 / 267
= 1
Step3:
LCM(1, 561) = 561
GCD(1, 561) = ( 1 x 561 ) / 561
= 1 / 561
= 1
So, Greatest Common Divisor of 287, 478, 267, 561 is 1
