Given numbers are 430, 428, 855, 134
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 428) = 92020
GCD(430, 428) = ( 430 x 428 ) / 92020
= 430 / 428
= 430
Step2:
LCM(2, 855) = 1710
GCD(2, 855) = ( 2 x 855 ) / 1710
= 2 / 855
= 2
Step3:
LCM(1, 134) = 134
GCD(1, 134) = ( 1 x 134 ) / 134
= 1 / 134
= 1
So, Greatest Common Divisor of 430, 428, 855, 134 is 1
