Calculate the LCM of 142,714,805

Given numbers are 142,714,805

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

The LCM of 142,714,805 is 5829810.

Find LCM of 142,714,805 with Prime Factorization


2 142, 714, 805
7 71, 357, 805
71, 51, 115

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

2 x 7 x 71 x 51 x 115 = 5829810

Therefore, the lowest common multiple of 142,714,805 is 5829810.

LCM Formula to Find Lowest Common Multiple of 142,714,805

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.

142 x 714 x 805 = 81617340

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.

142 : 1, 2, 71, 142

714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714

805 : 1, 5, 7, 23, 35, 115, 161, 805

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 142,714,805, is 1.

Now, the common factors can be found like this.

142:2x 71

714:2x 3x 7x 17

805:5x 7x 23

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

2x 7 = 14

Therefore, the value for common factors is 14.

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 = 81617340/(1x14)

LCM = 81617340/14

LCM = 5829810

Thus, we can understand that the LCM of 142,714,805 is 5829810.
