Given numbers are 504, 784, 644, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(504, 784) = 7056
GCD(504, 784) = ( 504 x 784 ) / 7056
= 504 / 784
= 504
Step2:
LCM(56, 644) = 1288
GCD(56, 644) = ( 56 x 644 ) / 1288
= 56 / 644
= 56
Step3:
LCM(28, 223) = 6244
GCD(28, 223) = ( 28 x 223 ) / 6244
= 28 / 223
= 28
So, Greatest Common Divisor of 504, 784, 644, 223 is 1
