Given numbers are 154, 649, 64, 859

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

Apply this formula for all numbers.

Step1:

LCM(154, 649) = 9086

GCD(154, 649) = ( 154 x 649 ) / 9086

= 154 / 649

= 154

Step2:

LCM(11, 64) = 704

GCD(11, 64) = ( 11 x 64 ) / 704

= 11 / 64

= 11

Step3:

LCM(1, 859) = 859

GCD(1, 859) = ( 1 x 859 ) / 859

= 1 / 859

= 1

So, Greatest Common Divisor of 154, 649, 64, 859 is 1
