GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(287, 248) = 71176
GCD(287, 248) = ( 287 x 248 ) / 71176
= 287 / 248
= 287
Step2:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
Step3:
LCM(1, 625) = 625
GCD(1, 625) = ( 1 x 625 ) / 625
= 1 / 625
= 1
So, Greatest Common Divisor of 287, 248, 820, 625 is 1
