Given numbers are 155, 825, 212, 279

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

Apply this formula for all numbers.

Step1:

LCM(155, 825) = 25575

GCD(155, 825) = ( 155 x 825 ) / 25575

= 155 / 825

= 155

Step2:

LCM(5, 212) = 1060

GCD(5, 212) = ( 5 x 212 ) / 1060

= 5 / 212

= 5

Step3:

LCM(1, 279) = 279

GCD(1, 279) = ( 1 x 279 ) / 279

= 1 / 279

= 1

So, Greatest Common Divisor of 155, 825, 212, 279 is 1
