GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(378, 777) = 13986
GCD(378, 777) = ( 378 x 777 ) / 13986
= 378 / 777
= 378
Step2:
LCM(21, 921) = 6447
GCD(21, 921) = ( 21 x 921 ) / 6447
= 21 / 921
= 21
Step3:
LCM(3, 224) = 672
GCD(3, 224) = ( 3 x 224 ) / 672
= 3 / 224
= 3
So, Greatest Common Divisor of 378, 777, 921, 224 is 1
