Given numbers are 278, 710, 948, 661

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

Apply this formula for all numbers.

Step1:

LCM(278, 710) = 98690

GCD(278, 710) = ( 278 x 710 ) / 98690

= 278 / 710

= 278

Step2:

LCM(2, 948) = 948

GCD(2, 948) = ( 2 x 948 ) / 948

= 2 / 948

= 2

Step3:

LCM(2, 661) = 1322

GCD(2, 661) = ( 2 x 661 ) / 1322

= 2 / 661

= 2

So, Greatest Common Divisor of 278, 710, 948, 661 is 1
