Given numbers are 642, 266, 338, 907

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

Apply this formula for all numbers.

Step1:

LCM(642, 266) = 85386

GCD(642, 266) = ( 642 x 266 ) / 85386

= 642 / 266

= 642

Step2:

LCM(2, 338) = 338

GCD(2, 338) = ( 2 x 338 ) / 338

= 2 / 338

= 2

Step3:

LCM(2, 907) = 1814

GCD(2, 907) = ( 2 x 907 ) / 1814

= 2 / 907

= 2

So, Greatest Common Divisor of 642, 266, 338, 907 is 1
