Given numbers are 503, 721, 672, 320
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(503, 721) = 362663
GCD(503, 721) = ( 503 x 721 ) / 362663
= 503 / 721
= 503
Step2:
LCM(1, 672) = 672
GCD(1, 672) = ( 1 x 672 ) / 672
= 1 / 672
= 1
Step3:
LCM(1, 320) = 320
GCD(1, 320) = ( 1 x 320 ) / 320
= 1 / 320
= 1
So, Greatest Common Divisor of 503, 721, 672, 320 is 1
