Given numbers are 420, 413, 689, 250
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 413) = 24780
GCD(420, 413) = ( 420 x 413 ) / 24780
= 420 / 413
= 420
Step2:
LCM(7, 689) = 4823
GCD(7, 689) = ( 7 x 689 ) / 4823
= 7 / 689
= 7
Step3:
LCM(1, 250) = 250
GCD(1, 250) = ( 1 x 250 ) / 250
= 1 / 250
= 1
So, Greatest Common Divisor of 420, 413, 689, 250 is 1
