Given numbers are 361, 861, 155, 902

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

Apply this formula for all numbers.

Step1:

LCM(361, 861) = 310821

GCD(361, 861) = ( 361 x 861 ) / 310821

= 361 / 861

= 361

Step2:

LCM(1, 155) = 155

GCD(1, 155) = ( 1 x 155 ) / 155

= 1 / 155

= 1

Step3:

LCM(1, 902) = 902

GCD(1, 902) = ( 1 x 902 ) / 902

= 1 / 902

= 1

So, Greatest Common Divisor of 361, 861, 155, 902 is 1
