Given numbers are 360,640,291,493
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 360,640,291,493 is 275448960.
Find LCM of 360,640,291,493 with Prime Factorization
| 2 | 360, 640, 291, 493 |
| 2 | 180, 320, 291, 493 |
| 2 | 90, 160, 291, 493 |
| 3 | 45, 80, 291, 493 |
| 5 | 15, 80, 97, 493 |
| 3, 16, 97, 493 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 3 x 16 x 97 x 493 = 275448960
Therefore, the lowest common multiple of 360,640,291,493 is 275448960.
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.
360 x 640 x 291 x 493 = 33053875200
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.
360 : 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
291 : 1, 3, 97, 291
493 : 1, 17, 29, 493
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 360,640,291,493, is 1.
Now, the common factors can be found like this.
360:2x 2x 2x 3x 3x 5
640:2x 2x 2x 2x 2x 2x 2x 5
291:3x 97
493:17x 29
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 3x 5 = 120
Therefore, the value for common factors is 120.
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 = 33053875200/(1x120)
LCM = 33053875200/120
LCM = 275448960
Thus, we can understand that the LCM of 360,640,291,493 is 275448960.
