Given numbers are 152, 270, 644, 806

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

Apply this formula for all numbers.

Step1:

LCM(152, 270) = 20520

GCD(152, 270) = ( 152 x 270 ) / 20520

= 152 / 270

= 152

Step2:

LCM(2, 644) = 644

GCD(2, 644) = ( 2 x 644 ) / 644

= 2 / 644

= 2

Step3:

LCM(2, 806) = 806

GCD(2, 806) = ( 2 x 806 ) / 806

= 2 / 806

= 2

So, Greatest Common Divisor of 152, 270, 644, 806 is 2
