Given numbers are 291, 998, 47, 630

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(291, 998) = 290418

GCD(291, 998) = ( 291 x 998 ) / 290418

= 291 / 998

= 291

Step2:

LCM(1, 47) = 47

GCD(1, 47) = ( 1 x 47 ) / 47

= 1 / 47

= 1

Step3:

LCM(1, 630) = 630

GCD(1, 630) = ( 1 x 630 ) / 630

= 1 / 630

= 1

So, Greatest Common Divisor of 291, 998, 47, 630 is 1
