Given numbers are 905, 815, 400, 964

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

Apply this formula for all numbers.

Step1:

LCM(905, 815) = 147515

GCD(905, 815) = ( 905 x 815 ) / 147515

= 905 / 815

= 905

Step2:

LCM(5, 400) = 400

GCD(5, 400) = ( 5 x 400 ) / 400

= 5 / 400

= 5

Step3:

LCM(5, 964) = 4820

GCD(5, 964) = ( 5 x 964 ) / 4820

= 5 / 964

= 5

So, Greatest Common Divisor of 905, 815, 400, 964 is 1
