Calculate the LCM of 699,763,639,945

Given numbers are 699,763,639,945

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 699,763,639,945 is 1704011715.

Find LCM of 699,763,639,945 with Prime Factorization


3 699, 763, 639, 945
3 233, 763, 213, 315
7 233, 763, 71, 105
233, 109, 71, 15

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

3 x 3 x 7 x 233 x 109 x 71 x 15 = 1704011715

Therefore, the lowest common multiple of 699,763,639,945 is 1704011715.

LCM Formula to Find Lowest Common Multiple of 699,763,639,945

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.

699 x 763 x 639 x 945 = 322058214135

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.

699 : 1, 3, 233, 699

763 : 1, 7, 109, 763

639 : 1, 3, 9, 71, 213, 639

945 : 1, 3, 5, 7, 9, 15, 21, 27, 35, 45, 63, 105, 135, 189, 315, 945

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 699,763,639,945, is 1.

Now, the common factors can be found like this.

699:3x 233

763:7x 109

639:3x 3x 71

945:3x 3x 3x 5x 7

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

3x 3x 3x 7 = 189

Therefore, the value for common factors is 189.

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 = 322058214135/(1x189)

LCM = 322058214135/189

LCM = 1704011715

Thus, we can understand that the LCM of 699,763,639,945 is 1704011715.
