Given numbers are 224, 638, 249, 771
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(224, 638) = 71456
GCD(224, 638) = ( 224 x 638 ) / 71456
= 224 / 638
= 224
Step2:
LCM(2, 249) = 498
GCD(2, 249) = ( 2 x 249 ) / 498
= 2 / 249
= 2
Step3:
LCM(1, 771) = 771
GCD(1, 771) = ( 1 x 771 ) / 771
= 1 / 771
= 1
So, Greatest Common Divisor of 224, 638, 249, 771 is 1
