Given numbers are 955, 465, 423, 644

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

Apply this formula for all numbers.

Step1:

LCM(955, 465) = 88815

GCD(955, 465) = ( 955 x 465 ) / 88815

= 955 / 465

= 955

Step2:

LCM(5, 423) = 2115

GCD(5, 423) = ( 5 x 423 ) / 2115

= 5 / 423

= 5

Step3:

LCM(1, 644) = 644

GCD(1, 644) = ( 1 x 644 ) / 644

= 1 / 644

= 1

So, Greatest Common Divisor of 955, 465, 423, 644 is 1
