Find LCM of 979,621,477,805,370 with Prime Factorization
| 3 | 979, 621, 477, 805, 370 |
| 3 | 979, 207, 159, 805, 370 |
| 5 | 979, 69, 53, 805, 370 |
| 23 | 979, 69, 53, 161, 74 |
| 979, 3, 53, 7, 74 |
Multiply the prime numbers at the bottom and the left side.
3 x 3 x 5 x 23 x 979 x 3 x 53 x 7 x 74 = 83454531930
Therefore, the lowest common multiple of 979,621,477,805,370 is 83454531930.
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.
979 x 621 x 477 x 805 x 370 = 86375440547550
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.
979 : 1, 11, 89, 979
621 : 1, 3, 9, 23, 27, 69, 207, 621
477 : 1, 3, 9, 53, 159, 477
805 : 1, 5, 7, 23, 35, 115, 161, 805
370 : 1, 2, 5, 10, 37, 74, 185, 370
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 979,621,477,805,370, is 1.
Now, the common factors can be found like this.
979:11x 89
621:3x 3x 3x 23
477:3x 3x 53
805:5x 7x 23
370:2x 5x 37
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 5x 23 = 1035
Therefore, the value for common factors is 1035.
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 = 86375440547550/(1x1035)
LCM = 86375440547550/1035
LCM = 83454531930
Thus, we can understand that the LCM of 979,621,477,805,370 is 83454531930.
