The LCM of 969,656,391,670 is 4897791120.

Find LCM of 969,656,391,670 with Prime Factorization


2 969, 656, 391, 670
17 969, 328, 391, 335
57, 328, 23, 335

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

2 x 17 x 57 x 328 x 23 x 335 = 4897791120

Therefore, the lowest common multiple of 969,656,391,670 is 4897791120.

LCM Formula to Find Lowest Common Multiple of 969,656,391,670

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.

969 x 656 x 391 x 670 = 166524898080

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.

969 : 1, 3, 17, 19, 51, 57, 323, 969

656 : 1, 2, 4, 8, 16, 41, 82, 164, 328, 656

391 : 1, 17, 23, 391

670 : 1, 2, 5, 10, 67, 134, 335, 670

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 969,656,391,670, is 1.

Now, the common factors can be found like this.

969:3x 17x 19

656:2x 2x 2x 2x 41

391:17x 23

670:2x 5x 67

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

2x 17 = 34

Therefore, the value for common factors is 34.

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 = 166524898080/(1x34)

LCM = 166524898080/34

LCM = 4897791120

Thus, we can understand that the LCM of 969,656,391,670 is 4897791120.
