Given numbers are 653, 765, 730, 115

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

Apply this formula for all numbers.

Step1:

LCM(653, 765) = 499545

GCD(653, 765) = ( 653 x 765 ) / 499545

= 653 / 765

= 653

Step2:

LCM(1, 730) = 730

GCD(1, 730) = ( 1 x 730 ) / 730

= 1 / 730

= 1

Step3:

LCM(1, 115) = 115

GCD(1, 115) = ( 1 x 115 ) / 115

= 1 / 115

= 1

So, Greatest Common Divisor of 653, 765, 730, 115 is 1
