GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(297, 630) = 20790
GCD(297, 630) = ( 297 x 630 ) / 20790
= 297 / 630
= 297
Step2:
LCM(9, 628) = 5652
GCD(9, 628) = ( 9 x 628 ) / 5652
= 9 / 628
= 9
Step3:
LCM(1, 890) = 890
GCD(1, 890) = ( 1 x 890 ) / 890
= 1 / 890
= 1
So, Greatest Common Divisor of 297, 630, 628, 890 is 1
