Given numbers are 645, 978, 88, 564

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

Apply this formula for all numbers.

Step1:

LCM(645, 978) = 210270

GCD(645, 978) = ( 645 x 978 ) / 210270

= 645 / 978

= 645

Step2:

LCM(3, 88) = 264

GCD(3, 88) = ( 3 x 88 ) / 264

= 3 / 88

= 3

Step3:

LCM(1, 564) = 564

GCD(1, 564) = ( 1 x 564 ) / 564

= 1 / 564

= 1

So, Greatest Common Divisor of 645, 978, 88, 564 is 1
