Given numbers are 429, 630, 422, 280
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 630) = 90090
GCD(429, 630) = ( 429 x 630 ) / 90090
= 429 / 630
= 429
Step2:
LCM(3, 422) = 1266
GCD(3, 422) = ( 3 x 422 ) / 1266
= 3 / 422
= 3
Step3:
LCM(1, 280) = 280
GCD(1, 280) = ( 1 x 280 ) / 280
= 1 / 280
= 1
So, Greatest Common Divisor of 429, 630, 422, 280 is 1
