Given numbers are 219, 406, 450, 861
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(219, 406) = 88914
GCD(219, 406) = ( 219 x 406 ) / 88914
= 219 / 406
= 219
Step2:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
Step3:
LCM(1, 861) = 861
GCD(1, 861) = ( 1 x 861 ) / 861
= 1 / 861
= 1
So, Greatest Common Divisor of 219, 406, 450, 861 is 1
