Given numbers are 430, 906, 861, 828
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(430, 906) = 194790
GCD(430, 906) = ( 430 x 906 ) / 194790
= 430 / 906
= 430
Step2:
LCM(2, 861) = 1722
GCD(2, 861) = ( 2 x 861 ) / 1722
= 2 / 861
= 2
Step3:
LCM(1, 828) = 828
GCD(1, 828) = ( 1 x 828 ) / 828
= 1 / 828
= 1
So, Greatest Common Divisor of 430, 906, 861, 828 is 1
