Calculate the LCM of 845,448,748,221

Given numbers are 845,448,748,221

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

The LCM of 845,448,748,221 is 70790720.

Find LCM of 845,448,748,221 with Prime Factorization


2 845, 448, 748, 221
2 845, 224, 374, 221
13 845, 112, 187, 221
17 65, 112, 187, 17
65, 112, 11, 1

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

2 x 2 x 13 x 17 x 65 x 112 x 11 x 1 = 70790720

Therefore, the lowest common multiple of 845,448,748,221 is 70790720.

LCM Formula to Find Lowest Common Multiple of 845,448,748,221

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.

845 x 448 x 748 x 221 = 62578996480

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.

845 : 1, 5, 13, 65, 169, 845

448 : 1, 2, 4, 7, 8, 14, 16, 28, 32, 56, 64, 112, 224, 448

748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748

221 : 1, 13, 17, 221

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 845,448,748,221, is 1.

Now, the common factors can be found like this.

845:5x 13x 13

448:2x 2x 2x 2x 2x 2x 7

748:2x 2x 11x 17

221:13x 17

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 13x 17 = 884

Therefore, the value for common factors is 884.

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 = 62578996480/(1x884)

LCM = 62578996480/884

LCM = 70790720

Thus, we can understand that the LCM of 845,448,748,221 is 70790720.
