Given numbers are 287, 518, 621, 118
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 518) = 21238
GCD(287, 518) = ( 287 x 518 ) / 21238
= 287 / 518
= 287
Step2:
LCM(7, 621) = 4347
GCD(7, 621) = ( 7 x 621 ) / 4347
= 7 / 621
= 7
Step3:
LCM(1, 118) = 118
GCD(1, 118) = ( 1 x 118 ) / 118
= 1 / 118
= 1
So, Greatest Common Divisor of 287, 518, 621, 118 is 1
