Given numbers are 287, 613, 290, 423
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 613) = 175931
GCD(287, 613) = ( 287 x 613 ) / 175931
= 287 / 613
= 287
Step2:
LCM(1, 290) = 290
GCD(1, 290) = ( 1 x 290 ) / 290
= 1 / 290
= 1
Step3:
LCM(1, 423) = 423
GCD(1, 423) = ( 1 x 423 ) / 423
= 1 / 423
= 1
So, Greatest Common Divisor of 287, 613, 290, 423 is 1
