Given numbers are 430, 985, 353, 109
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 985) = 84710
GCD(430, 985) = ( 430 x 985 ) / 84710
= 430 / 985
= 430
Step2:
LCM(5, 353) = 1765
GCD(5, 353) = ( 5 x 353 ) / 1765
= 5 / 353
= 5
Step3:
LCM(1, 109) = 109
GCD(1, 109) = ( 1 x 109 ) / 109
= 1 / 109
= 1
So, Greatest Common Divisor of 430, 985, 353, 109 is 1
