Given numbers are 278, 690, 533, 349

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

Apply this formula for all numbers.

Step1:

LCM(278, 690) = 95910

GCD(278, 690) = ( 278 x 690 ) / 95910

= 278 / 690

= 278

Step2:

LCM(2, 533) = 1066

GCD(2, 533) = ( 2 x 533 ) / 1066

= 2 / 533

= 2

Step3:

LCM(1, 349) = 349

GCD(1, 349) = ( 1 x 349 ) / 349

= 1 / 349

= 1

So, Greatest Common Divisor of 278, 690, 533, 349 is 1
