Given numbers are 249, 630, 637, 147
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(249, 630) = 52290
GCD(249, 630) = ( 249 x 630 ) / 52290
= 249 / 630
= 249
Step2:
LCM(3, 637) = 1911
GCD(3, 637) = ( 3 x 637 ) / 1911
= 3 / 637
= 3
Step3:
LCM(1, 147) = 147
GCD(1, 147) = ( 1 x 147 ) / 147
= 1 / 147
= 1
So, Greatest Common Divisor of 249, 630, 637, 147 is 1
