Given numbers are 868, 780, 447, 418
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(868, 780) = 169260
GCD(868, 780) = ( 868 x 780 ) / 169260
= 868 / 780
= 868
Step2:
LCM(4, 447) = 1788
GCD(4, 447) = ( 4 x 447 ) / 1788
= 4 / 447
= 4
Step3:
LCM(1, 418) = 418
GCD(1, 418) = ( 1 x 418 ) / 418
= 1 / 418
= 1
So, Greatest Common Divisor of 868, 780, 447, 418 is 1
