Given numbers are 870, 402, 454, 868

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

Apply this formula for all numbers.

Step1:

LCM(870, 402) = 58290

GCD(870, 402) = ( 870 x 402 ) / 58290

= 870 / 402

= 870

Step2:

LCM(6, 454) = 1362

GCD(6, 454) = ( 6 x 454 ) / 1362

= 6 / 454

= 6

Step3:

LCM(2, 868) = 868

GCD(2, 868) = ( 2 x 868 ) / 868

= 2 / 868

= 2

So, Greatest Common Divisor of 870, 402, 454, 868 is 2
