Calculate the LCM of 280,747,980,859

Given numbers are 280,747,980,859

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

The LCM of 280,747,980,859 is 1257679080.

Find LCM of 280,747,980,859 with Prime Factorization


2 280, 747, 980, 859
2 140, 747, 490, 859
5 70, 747, 245, 859
7 14, 747, 49, 859
2, 747, 7, 859

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

2 x 2 x 5 x 7 x 2 x 747 x 7 x 859 = 1257679080

Therefore, the lowest common multiple of 280,747,980,859 is 1257679080.

LCM Formula to Find Lowest Common Multiple of 280,747,980,859

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.

280 x 747 x 980 x 859 = 176075071200

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.

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

747 : 1, 3, 9, 83, 249, 747

980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980

859 : 1, 859

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 280,747,980,859, is 1.

Now, the common factors can be found like this.

280:2x 2x 2x 5x 7

747:3x 3x 83

980:2x 2x 5x 7x 7

859:859

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 5x 7 = 140

Therefore, the value for common factors is 140.

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 = 176075071200/(1x140)

LCM = 176075071200/140

LCM = 1257679080

Thus, we can understand that the LCM of 280,747,980,859 is 1257679080.
