Given numbers are 430, 196, 612, 985
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 196) = 42140
GCD(430, 196) = ( 430 x 196 ) / 42140
= 430 / 196
= 430
Step2:
LCM(2, 612) = 612
GCD(2, 612) = ( 2 x 612 ) / 612
= 2 / 612
= 2
Step3:
LCM(2, 985) = 1970
GCD(2, 985) = ( 2 x 985 ) / 1970
= 2 / 985
= 2
So, Greatest Common Divisor of 430, 196, 612, 985 is 1
