Given numbers are 645, 840, 11, 967

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

Apply this formula for all numbers.

Step1:

LCM(645, 840) = 36120

GCD(645, 840) = ( 645 x 840 ) / 36120

= 645 / 840

= 645

Step2:

LCM(15, 11) = 165

GCD(15, 11) = ( 15 x 11 ) / 165

= 15 / 11

= 15

Step3:

LCM(1, 967) = 967

GCD(1, 967) = ( 1 x 967 ) / 967

= 1 / 967

= 1

So, Greatest Common Divisor of 645, 840, 11, 967 is 1
