Given numbers are 815, 545, 366, 688

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

Apply this formula for all numbers.

Step1:

LCM(815, 545) = 88835

GCD(815, 545) = ( 815 x 545 ) / 88835

= 815 / 545

= 815

Step2:

LCM(5, 366) = 1830

GCD(5, 366) = ( 5 x 366 ) / 1830

= 5 / 366

= 5

Step3:

LCM(1, 688) = 688

GCD(1, 688) = ( 1 x 688 ) / 688

= 1 / 688

= 1

So, Greatest Common Divisor of 815, 545, 366, 688 is 1
