Given numbers are 920, 848, 393, 639

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

Apply this formula for all numbers.

Step1:

LCM(920, 848) = 97520

GCD(920, 848) = ( 920 x 848 ) / 97520

= 920 / 848

= 920

Step2:

LCM(8, 393) = 3144

GCD(8, 393) = ( 8 x 393 ) / 3144

= 8 / 393

= 8

Step3:

LCM(1, 639) = 639

GCD(1, 639) = ( 1 x 639 ) / 639

= 1 / 639

= 1

So, Greatest Common Divisor of 920, 848, 393, 639 is 1
