Given numbers are 830, 406, 245, 878
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 406) = 168490
GCD(830, 406) = ( 830 x 406 ) / 168490
= 830 / 406
= 830
Step2:
LCM(2, 245) = 490
GCD(2, 245) = ( 2 x 245 ) / 490
= 2 / 245
= 2
Step3:
LCM(1, 878) = 878
GCD(1, 878) = ( 1 x 878 ) / 878
= 1 / 878
= 1
So, Greatest Common Divisor of 830, 406, 245, 878 is 1
