Given numbers are 701,480,440,690
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 701,480,440,690 is 85129440.
Find LCM of 701,480,440,690 with Prime Factorization
| 2 | 701, 480, 440, 690 |
| 2 | 701, 240, 220, 345 |
| 2 | 701, 120, 110, 345 |
| 3 | 701, 60, 55, 345 |
| 5 | 701, 20, 55, 115 |
| 701, 4, 11, 23 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 701 x 4 x 11 x 23 = 85129440
Therefore, the lowest common multiple of 701,480,440,690 is 85129440.
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.
701 x 480 x 440 x 690 = 102155328000
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.
701 : 1, 701
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
440 : 1, 2, 4, 5, 8, 10, 11, 20, 22, 40, 44, 55, 88, 110, 220, 440
690 : 1, 2, 3, 5, 6, 10, 15, 23, 30, 46, 69, 115, 138, 230, 345, 690
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 701,480,440,690, is 1.
Now, the common factors can be found like this.
701:701
480:2x 2x 2x 2x 2x 3x 5
440:2x 2x 2x 5x 11
690:2x 3x 5x 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 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 = 102155328000/(1x1200)
LCM = 102155328000/1200
LCM = 85129440
Thus, we can understand that the LCM of 701,480,440,690 is 85129440.
