Calculate the LCM of 946,210,155,210

Given numbers are 946,210,155,210

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

The LCM of 946,210,155,210 is 3079230.

Find LCM of 946,210,155,210 with Prime Factorization


2 946, 210, 155, 210
3 473, 105, 155, 105
5 473, 35, 155, 35
7 473, 7, 31, 7
473, 1, 31, 1

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

2 x 3 x 5 x 7 x 473 x 1 x 31 x 1 = 3079230

Therefore, the lowest common multiple of 946,210,155,210 is 3079230.

LCM Formula to Find Lowest Common Multiple of 946,210,155,210

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.

946 x 210 x 155 x 210 = 6466383000

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.

946 : 1, 2, 11, 22, 43, 86, 473, 946

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

155 : 1, 5, 31, 155

210 : 1, 2, 3, 5, 6, 7, 10, 14, 15, 21, 30, 35, 42, 70, 105, 210

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,210,155,210, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

210:2x 3x 5x 7

155:5x 31

210:2x 3x 5x 7

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 3x 5x 5x 7 = 2100

Therefore, the value for common factors is 2100.

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 = 6466383000/(1x2100)

LCM = 6466383000/2100

LCM = 3079230

Thus, we can understand that the LCM of 946,210,155,210 is 3079230.
