Given numbers are 278, 990, 264, 619

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

Apply this formula for all numbers.

Step1:

LCM(278, 990) = 137610

GCD(278, 990) = ( 278 x 990 ) / 137610

= 278 / 990

= 278

Step2:

LCM(2, 264) = 264

GCD(2, 264) = ( 2 x 264 ) / 264

= 2 / 264

= 2

Step3:

LCM(2, 619) = 1238

GCD(2, 619) = ( 2 x 619 ) / 1238

= 2 / 619

= 2

So, Greatest Common Divisor of 278, 990, 264, 619 is 1
