Given numbers are 165, 906, 775, 784

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

Apply this formula for all numbers.

Step1:

LCM(165, 906) = 49830

GCD(165, 906) = ( 165 x 906 ) / 49830

= 165 / 906

= 165

Step2:

LCM(3, 775) = 2325

GCD(3, 775) = ( 3 x 775 ) / 2325

= 3 / 775

= 3

Step3:

LCM(1, 784) = 784

GCD(1, 784) = ( 1 x 784 ) / 784

= 1 / 784

= 1

So, Greatest Common Divisor of 165, 906, 775, 784 is 1
