Given numbers are 561,102,291,456,695
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 561,102,291,456,695 is 5748611880.
Find LCM of 561,102,291,456,695 with Prime Factorization
| 2 | 561, 102, 291, 456, 695 |
| 3 | 561, 51, 291, 228, 695 |
| 17 | 187, 17, 97, 76, 695 |
| 11, 1, 97, 76, 695 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 17 x 11 x 1 x 97 x 76 x 695 = 5748611880
Therefore, the lowest common multiple of 561,102,291,456,695 is 5748611880.
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.
561 x 102 x 291 x 456 x 695 = 5277225705840
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.
561 : 1, 3, 11, 17, 33, 51, 187, 561
102 : 1, 2, 3, 6, 17, 34, 51, 102
291 : 1, 3, 97, 291
456 : 1, 2, 3, 4, 6, 8, 12, 19, 24, 38, 57, 76, 114, 152, 228, 456
695 : 1, 5, 139, 695
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 561,102,291,456,695, is 1.
Now, the common factors can be found like this.
561:3x 11x 17
102:2x 3x 17
291:3x 97
456:2x 2x 2x 3x 19
695:5x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 3x 17 = 918
Therefore, the value for common factors is 918.
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 = 5277225705840/(1x918)
LCM = 5277225705840/918
LCM = 5748611880
Thus, we can understand that the LCM of 561,102,291,456,695 is 5748611880.
