Given numbers are 609, 253, 278, 655

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

Apply this formula for all numbers.

Step1:

LCM(609, 253) = 154077

GCD(609, 253) = ( 609 x 253 ) / 154077

= 609 / 253

= 609

Step2:

LCM(1, 278) = 278

GCD(1, 278) = ( 1 x 278 ) / 278

= 1 / 278

= 1

Step3:

LCM(1, 655) = 655

GCD(1, 655) = ( 1 x 655 ) / 655

= 1 / 655

= 1

So, Greatest Common Divisor of 609, 253, 278, 655 is 1
