Given numbers are 420, 178, 956, 953
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(420, 178) = 37380
GCD(420, 178) = ( 420 x 178 ) / 37380
= 420 / 178
= 420
Step2:
LCM(2, 956) = 956
GCD(2, 956) = ( 2 x 956 ) / 956
= 2 / 956
= 2
Step3:
LCM(2, 953) = 1906
GCD(2, 953) = ( 2 x 953 ) / 1906
= 2 / 953
= 2
So, Greatest Common Divisor of 420, 178, 956, 953 is 1
