Given numbers are 430,120,680,534
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,120,680,534 is 7807080.
Find LCM of 430,120,680,534 with Prime Factorization
| 2 | 430, 120, 680, 534 |
| 2 | 215, 60, 340, 267 |
| 2 | 215, 30, 170, 267 |
| 3 | 215, 15, 85, 267 |
| 5 | 215, 5, 85, 89 |
| 43, 1, 17, 89 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 43 x 1 x 17 x 89 = 7807080
Therefore, the lowest common multiple of 430,120,680,534 is 7807080.
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.
430 x 120 x 680 x 534 = 18736992000
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
120 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 20, 24, 30, 40, 60, 120
680 : 1, 2, 4, 5, 8, 10, 17, 20, 34, 40, 68, 85, 136, 170, 340, 680
534 : 1, 2, 3, 6, 89, 178, 267, 534
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,120,680,534, is 2.
Now, the common factors can be found like this.
430:2x 5x 43
120:2x 2x 2x 3x 5
680:2x 2x 2x 5x 17
534:2x 3x 89
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 3x 5x 5 = 1200
Therefore, the value for common factors is 1200.
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 = 18736992000/(2x1200)
LCM = 18736992000/2400
LCM = 7807080
Thus, we can understand that the LCM of 430,120,680,534 is 7807080.
