Given numbers are 128, 692, 80, 918

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

Apply this formula for all numbers.

Step1:

LCM(128, 692) = 22144

GCD(128, 692) = ( 128 x 692 ) / 22144

= 128 / 692

= 128

Step2:

LCM(4, 80) = 80

GCD(4, 80) = ( 4 x 80 ) / 80

= 4 / 80

= 4

Step3:

LCM(4, 918) = 1836

GCD(4, 918) = ( 4 x 918 ) / 1836

= 4 / 918

= 4

So, Greatest Common Divisor of 128, 692, 80, 918 is 2
