Given numbers are 7730,1786

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

The LCM of 7730,1786 is 6902890.

Find LCM of 7730,1786 with Prime Factorization

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

2 x 3865 x 893 = 6902890

Therefore, the lowest common multiple of 7730,1786 is 6902890.

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.

7730 x 1786 = 13805780

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.

7730 : 1, 2, 5, 10, 773, 1546, 3865, 7730

1786 : 1, 2, 19, 38, 47, 94, 893, 1786

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 7730,1786, is 2.

Now, the common factors can be found like this.

7730:2x 5x 773

1786:2x 19x 47

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

= 1

Therefore, the value for common factors is 1.

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 = 13805780/(2x1)

LCM = 13805780/2

LCM = 6902890

Thus, we can understand that the LCM of 7730,1786 is 6902890.

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

• LCM of 4656, 2006
• LCM of 5347, 4679
