Given numbers are 470, 220, 419, 223
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(470, 220) = 10340
GCD(470, 220) = ( 470 x 220 ) / 10340
= 470 / 220
= 470
Step2:
LCM(10, 419) = 4190
GCD(10, 419) = ( 10 x 419 ) / 4190
= 10 / 419
= 10
Step3:
LCM(1, 223) = 223
GCD(1, 223) = ( 1 x 223 ) / 223
= 1 / 223
= 1
So, Greatest Common Divisor of 470, 220, 419, 223 is 1
