The LCM of 946,882,978,815 is 340006590.

Find LCM of 946,882,978,815 with Prime Factorization


2 946, 882, 978, 815
3 473, 441, 489, 815
163 473, 147, 163, 815
473, 147, 1, 5

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

2 x 3 x 163 x 473 x 147 x 1 x 5 = 340006590

Therefore, the lowest common multiple of 946,882,978,815 is 340006590.

LCM Formula to Find Lowest Common Multiple of 946,882,978,815

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 882 x 978 x 815 = 665052890040

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

882 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 42, 49, 63, 98, 126, 147, 294, 441, 882

978 : 1, 2, 3, 6, 163, 326, 489, 978

815 : 1, 5, 163, 815

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 946,882,978,815, is 1.

Now, the common factors can be found like this.

946:2x 11x 43

882:2x 3x 3x 7x 7

978:2x 3x 163

815:5x 163

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 163 = 1956

Therefore, the value for common factors is 1956.

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 = 665052890040/(1x1956)

LCM = 665052890040/1956

LCM = 340006590

Thus, we can understand that the LCM of 946,882,978,815 is 340006590.
