Given numbers are 420, 261, 159, 936
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 261) = 36540
GCD(420, 261) = ( 420 x 261 ) / 36540
= 420 / 261
= 420
Step2:
LCM(3, 159) = 159
GCD(3, 159) = ( 3 x 159 ) / 159
= 3 / 159
= 3
Step3:
LCM(3, 936) = 936
GCD(3, 936) = ( 3 x 936 ) / 936
= 3 / 936
= 3
So, Greatest Common Divisor of 420, 261, 159, 936 is 3
