Given numbers are 655,490,524,681
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 655,490,524,681 is 87426780.
Find LCM of 655,490,524,681 with Prime Factorization
| 2 | 655, 490, 524, 681 |
| 5 | 655, 245, 262, 681 |
| 131 | 131, 49, 262, 681 |
| 1, 49, 2, 681 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 131 x 1 x 49 x 2 x 681 = 87426780
Therefore, the lowest common multiple of 655,490,524,681 is 87426780.
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 490 x 524 x 681 = 114529081800
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
490 : 1, 2, 5, 7, 10, 14, 35, 49, 70, 98, 245, 490
524 : 1, 2, 4, 131, 262, 524
681 : 1, 3, 227, 681
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 655,490,524,681, is 1.
Now, the common factors can be found like this.
655:5x 131
490:2x 5x 7x 7
524:2x 2x 131
681:3x 227
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 131 = 1310
Therefore, the value for common factors is 1310.
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 = 114529081800/(1x1310)
LCM = 114529081800/1310
LCM = 87426780
Thus, we can understand that the LCM of 655,490,524,681 is 87426780.
