Given numbers are 620, 275, 78, 262

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

Apply this formula for all numbers.

Step1:

LCM(620, 275) = 34100

GCD(620, 275) = ( 620 x 275 ) / 34100

= 620 / 275

= 620

Step2:

LCM(5, 78) = 390

GCD(5, 78) = ( 5 x 78 ) / 390

= 5 / 78

= 5

Step3:

LCM(1, 262) = 262

GCD(1, 262) = ( 1 x 262 ) / 262

= 1 / 262

= 1

So, Greatest Common Divisor of 620, 275, 78, 262 is 1
