Given numbers are 7,247,420,479

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

The LCM of 7,247,420,479 is 49691460.

Find LCM of 7,247,420,479 with Prime Factorization

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

7 x 1 x 247 x 60 x 479 = 49691460

Therefore, the lowest common multiple of 7,247,420,479 is 49691460.

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.

7 x 247 x 420 x 479 = 347840220

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.

7 : 1, 7

247 : 1, 13, 19, 247

420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420

479 : 1, 479

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7,247,420,479, is 1.

Now, the common factors can be found like this.

7:7

247:13x 19

420:2x 2x 3x 5x 7

479:479

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

7 = 7

Therefore, the value for common factors is 7.

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 = 347840220/(1x7)

LCM = 347840220/7

LCM = 49691460

Thus, we can understand that the LCM of 7,247,420,479 is 49691460.

Here are some samples of LCM of two or more Numbers calculations.

• LCM of 1, 573, 376, 844
