Given numbers are 165, 765, 155, 579

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

Apply this formula for all numbers.

Step1:

LCM(165, 765) = 8415

GCD(165, 765) = ( 165 x 765 ) / 8415

= 165 / 765

= 165

Step2:

LCM(15, 155) = 465

GCD(15, 155) = ( 15 x 155 ) / 465

= 15 / 155

= 15

Step3:

LCM(5, 579) = 2895

GCD(5, 579) = ( 5 x 579 ) / 2895

= 5 / 579

= 5

So, Greatest Common Divisor of 165, 765, 155, 579 is 1
