Given numbers are 440, 648, 270, 442

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

Apply this formula for all numbers.

Step1:

LCM(440, 648) = 35640

GCD(440, 648) = ( 440 x 648 ) / 35640

= 440 / 648

= 440

Step2:

LCM(8, 270) = 1080

GCD(8, 270) = ( 8 x 270 ) / 1080

= 8 / 270

= 8

Step3:

LCM(2, 442) = 442

GCD(2, 442) = ( 2 x 442 ) / 442

= 2 / 442

= 2

So, Greatest Common Divisor of 440, 648, 270, 442 is 2
