Given numbers are 440,428,532,969
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 440,428,532,969 is 319343640.
Find LCM of 440,428,532,969 with Prime Factorization
| 2 | 440, 428, 532, 969 |
| 2 | 220, 214, 266, 969 |
| 19 | 110, 107, 133, 969 |
| 110, 107, 7, 51 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 19 x 110 x 107 x 7 x 51 = 319343640
Therefore, the lowest common multiple of 440,428,532,969 is 319343640.
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.
440 x 428 x 532 x 969 = 97080466560
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.
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
428 : 1, 2, 4, 107, 214, 428
532 : 1, 2, 4, 7, 14, 19, 28, 38, 76, 133, 266, 532
969 : 1, 3, 17, 19, 51, 57, 323, 969
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 440,428,532,969, is 1.
Now, the common factors can be found like this.
440:2x 2x 2x 5x 11
428:2x 2x 107
532:2x 2x 7x 19
969:3x 17x 19
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 19 = 304
Therefore, the value for common factors is 304.
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 = 97080466560/(1x304)
LCM = 97080466560/304
LCM = 319343640
Thus, we can understand that the LCM of 440,428,532,969 is 319343640.
