Given numbers are 474,655,280,744
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 474,655,280,744 is 269487960.
Find LCM of 474,655,280,744 with Prime Factorization
| 2 | 474, 655, 280, 744 |
| 2 | 237, 655, 140, 372 |
| 2 | 237, 655, 70, 186 |
| 3 | 237, 655, 35, 93 |
| 5 | 79, 655, 35, 31 |
| 79, 131, 7, 31 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 2 x 3 x 5 x 79 x 131 x 7 x 31 = 269487960
Therefore, the lowest common multiple of 474,655,280,744 is 269487960.
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.
474 x 655 x 280 x 744 = 64677110400
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.
474 : 1, 2, 3, 6, 79, 158, 237, 474
655 : 1, 5, 131, 655
280 : 1, 2, 4, 5, 7, 8, 10, 14, 20, 28, 35, 40, 56, 70, 140, 280
744 : 1, 2, 3, 4, 6, 8, 12, 24, 31, 62, 93, 124, 186, 248, 372, 744
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 474,655,280,744, is 1.
Now, the common factors can be found like this.
474:2x 3x 79
655:5x 131
280:2x 2x 2x 5x 7
744:2x 2x 2x 3x 31
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 5 = 240
Therefore, the value for common factors is 240.
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 = 64677110400/(1x240)
LCM = 64677110400/240
LCM = 269487960
Thus, we can understand that the LCM of 474,655,280,744 is 269487960.
