Given numbers are 918, 478, 534, 646

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

Apply this formula for all numbers.

Step1:

LCM(918, 478) = 219402

GCD(918, 478) = ( 918 x 478 ) / 219402

= 918 / 478

= 918

Step2:

LCM(2, 534) = 534

GCD(2, 534) = ( 2 x 534 ) / 534

= 2 / 534

= 2

Step3:

LCM(2, 646) = 646

GCD(2, 646) = ( 2 x 646 ) / 646

= 2 / 646

= 2

So, Greatest Common Divisor of 918, 478, 534, 646 is 2
