Given numbers are 361, 247, 878, 402

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

Apply this formula for all numbers.

Step1:

LCM(361, 247) = 4693

GCD(361, 247) = ( 361 x 247 ) / 4693

= 361 / 247

= 361

Step2:

LCM(19, 878) = 16682

GCD(19, 878) = ( 19 x 878 ) / 16682

= 19 / 878

= 19

Step3:

LCM(1, 402) = 402

GCD(1, 402) = ( 1 x 402 ) / 402

= 1 / 402

= 1

So, Greatest Common Divisor of 361, 247, 878, 402 is 1
