Given numbers are 253, 642, 278

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

Apply this formula for all numbers.

Step1:

LCM(253, 642) = 162426

GCD(253, 642) = ( 253 x 642 ) / 162426

= 253 / 642

= 253

Step2:

LCM(1, 278) = 278

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

= 1 / 278

= 1

So, Greatest Common Divisor of 253, 642, 278 is 1
