Given numbers are 651,135,390,874
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 651,135,390,874 is 332849790.
Find LCM of 651,135,390,874 with Prime Factorization
| 2 | 651, 135, 390, 874 |
| 3 | 651, 135, 195, 437 |
| 5 | 217, 45, 65, 437 |
| 217, 9, 13, 437 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 217 x 9 x 13 x 437 = 332849790
Therefore, the lowest common multiple of 651,135,390,874 is 332849790.
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.
651 x 135 x 390 x 874 = 29956481100
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.
651 : 1, 3, 7, 21, 31, 93, 217, 651
135 : 1, 3, 5, 9, 15, 27, 45, 135
390 : 1, 2, 3, 5, 6, 10, 13, 15, 26, 30, 39, 65, 78, 130, 195, 390
874 : 1, 2, 19, 23, 38, 46, 437, 874
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 651,135,390,874, is 1.
Now, the common factors can be found like this.
651:3x 7x 31
135:3x 3x 3x 5
390:2x 3x 5x 13
874:2x 19x 23
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 5 = 90
Therefore, the value for common factors is 90.
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 = 29956481100/(1x90)
LCM = 29956481100/90
LCM = 332849790
Thus, we can understand that the LCM of 651,135,390,874 is 332849790.
