Find LCM of 180,912,968,490,861 with Prime Factorization
| 2 | 180, 912, 968, 490, 861 |
| 2 | 90, 456, 484, 245, 861 |
| 2 | 45, 228, 242, 245, 861 |
| 3 | 45, 114, 121, 245, 861 |
| 5 | 15, 38, 121, 245, 287 |
| 7 | 3, 38, 121, 49, 287 |
| 3, 38, 121, 7, 41 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 7 x 3 x 38 x 121 x 7 x 41 = 3325457520
Therefore, the lowest common multiple of 180,912,968,490,861 is 3325457520.
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.
180 x 912 x 968 x 490 x 861 = 67041223603200
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
912 : 1, 2, 3, 4, 6, 8, 12, 16, 19, 24, 38, 48, 57, 76, 114, 152, 228, 304, 456, 912
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
861 : 1, 3, 7, 21, 41, 123, 287, 861
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,912,968,490,861, is 1.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
912:2x 2x 2x 2x 3x 19
968:2x 2x 2x 11x 11
490:2x 5x 7x 7
861:3x 7x 41
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 2x 2x 2x 2x 3x 3x 5x 7 = 20160
Therefore, the value for common factors is 20160.
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 = 67041223603200/(1x20160)
LCM = 67041223603200/20160
LCM = 3325457520
Thus, we can understand that the LCM of 180,912,968,490,861 is 3325457520.
