Given numbers are 686,785,295,112,572
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 686,785,295,112,572 is 36347270960.
Find LCM of 686,785,295,112,572 with Prime Factorization
| 2 | 686, 785, 295, 112, 572 |
| 2 | 343, 785, 295, 56, 286 |
| 5 | 343, 785, 295, 28, 143 |
| 7 | 343, 157, 59, 28, 143 |
| 49, 157, 59, 4, 143 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 49 x 157 x 59 x 4 x 143 = 36347270960
Therefore, the lowest common multiple of 686,785,295,112,572 is 36347270960.
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.
686 x 785 x 295 x 112 x 572 = 10177235868800
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.
686 : 1, 2, 7, 14, 49, 98, 343, 686
785 : 1, 5, 157, 785
295 : 1, 5, 59, 295
112 : 1, 2, 4, 7, 8, 14, 16, 28, 56, 112
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 686,785,295,112,572, is 1.
Now, the common factors can be found like this.
686:2x 7x 7x 7
785:5x 157
295:5x 59
112:2x 2x 2x 2x 7
572:2x 2x 11x 13
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 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 10177235868800/(1x280)
LCM = 10177235868800/280
LCM = 36347270960
Thus, we can understand that the LCM of 686,785,295,112,572 is 36347270960.
