Given numbers are 661, 610, 622, 278

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

Apply this formula for all numbers.

Step1:

LCM(661, 610) = 403210

GCD(661, 610) = ( 661 x 610 ) / 403210

= 661 / 610

= 661

Step2:

LCM(1, 622) = 622

GCD(1, 622) = ( 1 x 622 ) / 622

= 1 / 622

= 1

Step3:

LCM(1, 278) = 278

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

= 1 / 278

= 1

So, Greatest Common Divisor of 661, 610, 622, 278 is 1
