Given numbers are 802,434,820

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

The LCM of 802,434,820 is 71353940.

Find LCM of 802,434,820 with Prime Factorization

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

2 x 401 x 217 x 410 = 71353940

Therefore, the lowest common multiple of 802,434,820 is 71353940.

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.

802 x 434 x 820 = 285415760

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.

802 : 1, 2, 401, 802

434 : 1, 2, 7, 14, 31, 62, 217, 434

820 : 1, 2, 4, 5, 10, 20, 41, 82, 164, 205, 410, 820

2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 802,434,820, is 2.

Now, the common factors can be found like this.

802:2x 401

434:2x 7x 31

820:2x 2x 5x 41

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

2 = 2

Therefore, the value for common factors is 2.

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 = 285415760/(2x2)

LCM = 285415760/4

LCM = 71353940

Thus, we can understand that the LCM of 802,434,820 is 71353940.

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

• LCM of 495, 776, 937
