Given numbers are 768, 144, 503, 220
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(768, 144) = 2304
GCD(768, 144) = ( 768 x 144 ) / 2304
= 768 / 144
= 768
Step2:
LCM(48, 503) = 24144
GCD(48, 503) = ( 48 x 503 ) / 24144
= 48 / 503
= 48
Step3:
LCM(1, 220) = 220
GCD(1, 220) = ( 1 x 220 ) / 220
= 1 / 220
= 1
So, Greatest Common Divisor of 768, 144, 503, 220 is 1
