Given numbers are 812, 856, 561, 414
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(812, 856) = 173768
GCD(812, 856) = ( 812 x 856 ) / 173768
= 812 / 856
= 812
Step2:
LCM(4, 561) = 2244
GCD(4, 561) = ( 4 x 561 ) / 2244
= 4 / 561
= 4
Step3:
LCM(1, 414) = 414
GCD(1, 414) = ( 1 x 414 ) / 414
= 1 / 414
= 1
So, Greatest Common Divisor of 812, 856, 561, 414 is 1
