Given numbers are 601,640,490,735
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 601,640,490,735 is 56542080.
Find LCM of 601,640,490,735 with Prime Factorization
| 2 | 601, 640, 490, 735 |
| 5 | 601, 320, 245, 735 |
| 7 | 601, 64, 49, 147 |
| 7 | 601, 64, 7, 21 |
| 601, 64, 1, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 7 x 601 x 64 x 1 x 3 = 56542080
Therefore, the lowest common multiple of 601,640,490,735 is 56542080.
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.
601 x 640 x 490 x 735 = 138528096000
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.
601 : 1, 601
640 : 1, 2, 4, 5, 8, 10, 16, 20, 32, 40, 64, 80, 128, 160, 320, 640
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 601,640,490,735, is 1.
Now, the common factors can be found like this.
601:601
640:2x 2x 2x 2x 2x 2x 2x 5
490:2x 5x 7x 7
735:3x 5x 7x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 5x 7x 7 = 2450
Therefore, the value for common factors is 2450.
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 = 138528096000/(1x2450)
LCM = 138528096000/2450
LCM = 56542080
Thus, we can understand that the LCM of 601,640,490,735 is 56542080.
