Given numbers are 429, 141, 639, 257
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(429, 141) = 20163
GCD(429, 141) = ( 429 x 141 ) / 20163
= 429 / 141
= 429
Step2:
LCM(3, 639) = 639
GCD(3, 639) = ( 3 x 639 ) / 639
= 3 / 639
= 3
Step3:
LCM(3, 257) = 771
GCD(3, 257) = ( 3 x 257 ) / 771
= 3 / 257
= 3
So, Greatest Common Divisor of 429, 141, 639, 257 is 1
