Find LCM of 888,391,238,121,717 with Prime Factorization


2 888, 391, 238, 121, 717
3 444, 391, 119, 121, 717
17 148, 391, 119, 121, 239
148, 23, 7, 121, 239

Multiply the prime numbers at the bottom and the left side.

2 x 3 x 17 x 148 x 23 x 7 x 121 x 239 = 70286357064

Therefore, the lowest common multiple of 888,391,238,121,717 is 70286357064.

LCM Formula to Find Lowest Common Multiple of 888,391,238,121,717

LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

Firstly, we have to find the product of all the numbers.

888 x 391 x 238 x 121 x 717 = 7169208420528

Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.

888 : 1, 2, 3, 4, 6, 8, 12, 24, 37, 74, 111, 148, 222, 296, 444, 888

391 : 1, 17, 23, 391

238 : 1, 2, 7, 14, 17, 34, 119, 238

121 : 1, 11, 121

717 : 1, 3, 239, 717

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 888,391,238,121,717, is 1.

Now, the common factors can be found like this.

888:2x 2x 2x 3x 37

391:17x 23

238:2x 7x 17

121:11x 11

717:3x 239

From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.

2x 3x 17 = 102

Therefore, the value for common factors is 102.

Now that we have all the elements of the formula, we can plug them in to calculate the LCM.

LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}

LCM = 7169208420528/(1x102)

LCM = 7169208420528/102

LCM = 70286357064

Thus, we can understand that the LCM of 888,391,238,121,717 is 70286357064.
