GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 224) = 10080
GCD(630, 224) = ( 630 x 224 ) / 10080
= 630 / 224
= 630
Step2:
LCM(14, 838) = 5866
GCD(14, 838) = ( 14 x 838 ) / 5866
= 14 / 838
= 14
Step3:
LCM(2, 278) = 278
GCD(2, 278) = ( 2 x 278 ) / 278
= 2 / 278
= 2
So, Greatest Common Divisor of 630, 224, 838, 278 is 2
