Given numbers are 655,140,473,524
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,140,473,524 is 8674820.
Find LCM of 655,140,473,524 with Prime Factorization
| 2 | 655, 140, 473, 524 |
| 2 | 655, 70, 473, 262 |
| 5 | 655, 35, 473, 131 |
| 131 | 131, 7, 473, 131 |
| 1, 7, 473, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 131 x 1 x 7 x 473 x 1 = 8674820
Therefore, the lowest common multiple of 655,140,473,524 is 8674820.
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.
655 x 140 x 473 x 524 = 22728028400
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.
655 : 1, 5, 131, 655
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
473 : 1, 11, 43, 473
524 : 1, 2, 4, 131, 262, 524
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,140,473,524, is 1.
Now, the common factors can be found like this.
655:5x 131
140:2x 2x 5x 7
473:11x 43
524:2x 2x 131
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 5x 131 = 2620
Therefore, the value for common factors is 2620.
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 = 22728028400/(1x2620)
LCM = 22728028400/2620
LCM = 8674820
Thus, we can understand that the LCM of 655,140,473,524 is 8674820.
