Given numbers are 420, 959, 778, 955

GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)

Apply this formula for all numbers.

Step1:

LCM(420, 959) = 57540

GCD(420, 959) = ( 420 x 959 ) / 57540

= 420 / 959

= 420

Step2:

LCM(7, 778) = 5446

GCD(7, 778) = ( 7 x 778 ) / 5446

= 7 / 778

= 7

Step3:

LCM(1, 955) = 955

GCD(1, 955) = ( 1 x 955 ) / 955

= 1 / 955

= 1

So, Greatest Common Divisor of 420, 959, 778, 955 is 1
