Find LCM of 874,704,560,861 with Prime Factorization


2 874, 704, 560, 861
2 437, 352, 280, 861
2 437, 176, 140, 861
2 437, 88, 70, 861
7 437, 44, 35, 861
437, 44, 5, 123

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

2 x 2 x 2 x 2 x 7 x 437 x 44 x 5 x 123 = 1324424640

Therefore, the lowest common multiple of 874,704,560,861 is 1324424640.

LCM Formula to Find Lowest Common Multiple of 874,704,560,861

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.

874 x 704 x 560 x 861 = 296671119360

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.

874 : 1, 2, 19, 23, 38, 46, 437, 874

704 : 1, 2, 4, 8, 11, 16, 22, 32, 44, 64, 88, 176, 352, 704

560 : 1, 2, 4, 5, 7, 8, 10, 14, 16, 20, 28, 35, 40, 56, 70, 80, 112, 140, 280, 560

861 : 1, 3, 7, 21, 41, 123, 287, 861

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 874,704,560,861, is 1.

Now, the common factors can be found like this.

874:2x 19x 23

704:2x 2x 2x 2x 2x 2x 11

560:2x 2x 2x 2x 5x 7

861:3x 7x 41

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

2x 2x 2x 2x 2x 7 = 224

Therefore, the value for common factors is 224.

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 = 296671119360/(1x224)

LCM = 296671119360/224

LCM = 1324424640

Thus, we can understand that the LCM of 874,704,560,861 is 1324424640.
