Given numbers are 695,280,124,462
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 695,280,124,462 is 39815160.
Find LCM of 695,280,124,462 with Prime Factorization
| 2 | 695, 280, 124, 462 |
| 2 | 695, 140, 62, 231 |
| 5 | 695, 70, 31, 231 |
| 7 | 139, 14, 31, 231 |
| 139, 2, 31, 33 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 139 x 2 x 31 x 33 = 39815160
Therefore, the lowest common multiple of 695,280,124,462 is 39815160.
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.
695 x 280 x 124 x 462 = 11148244800
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.
695 : 1, 5, 139, 695
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
124 : 1, 2, 4, 31, 62, 124
462 : 1, 2, 3, 6, 7, 11, 14, 21, 22, 33, 42, 66, 77, 154, 231, 462
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 695,280,124,462, is 1.
Now, the common factors can be found like this.
695:5x 139
280:2x 2x 2x 5x 7
124:2x 2x 31
462:2x 3x 7x 11
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 11148244800/(1x280)
LCM = 11148244800/280
LCM = 39815160
Thus, we can understand that the LCM of 695,280,124,462 is 39815160.
