Given numbers are 354, 290, 811, 815

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

Apply this formula for all numbers.

Step1:

LCM(354, 290) = 51330

GCD(354, 290) = ( 354 x 290 ) / 51330

= 354 / 290

= 354

Step2:

LCM(2, 811) = 1622

GCD(2, 811) = ( 2 x 811 ) / 1622

= 2 / 811

= 2

Step3:

LCM(1, 815) = 815

GCD(1, 815) = ( 1 x 815 ) / 815

= 1 / 815

= 1

So, Greatest Common Divisor of 354, 290, 811, 815 is 1
