Given numbers are 855, 278, 490, 524

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

Apply this formula for all numbers.

Step1:

LCM(855, 278) = 237690

GCD(855, 278) = ( 855 x 278 ) / 237690

= 855 / 278

= 855

Step2:

LCM(1, 490) = 490

GCD(1, 490) = ( 1 x 490 ) / 490

= 1 / 490

= 1

Step3:

LCM(1, 524) = 524

GCD(1, 524) = ( 1 x 524 ) / 524

= 1 / 524

= 1

So, Greatest Common Divisor of 855, 278, 490, 524 is 1
