Given numbers are 749,987,821

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

The LCM of 749,987,821 is 86704989.

Find LCM of 749,987,821 with Prime Factorization

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

7 x 107 x 141 x 821 = 86704989

Therefore, the lowest common multiple of 749,987,821 is 86704989.

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.

749 x 987 x 821 = 606934923

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.

749 : 1, 7, 107, 749

987 : 1, 3, 7, 21, 47, 141, 329, 987

821 : 1, 821

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 749,987,821, is 1.

Now, the common factors can be found like this.

749:7x 107

987:3x 7x 47

821:821

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 = 606934923/(1x7)

LCM = 606934923/7

LCM = 86704989

Thus, we can understand that the LCM of 749,987,821 is 86704989.

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

• LCM of 853, 613, 229
• LCM of 682, 657, 767
