Given numbers are 347,949,985,910,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 347,949,985,910,642 is 1457689366770.
Find LCM of 347,949,985,910,642 with Prime Factorization
| 2 | 347, 949, 985, 910, 642 |
| 5 | 347, 949, 985, 455, 321 |
| 13 | 347, 949, 197, 91, 321 |
| 347, 73, 197, 7, 321 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 347 x 73 x 197 x 7 x 321 = 1457689366770
Therefore, the lowest common multiple of 347,949,985,910,642 is 1457689366770.
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.
347 x 949 x 985 x 910 x 642 = 189499617680100
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.
347 : 1, 347
949 : 1, 13, 73, 949
985 : 1, 5, 197, 985
910 : 1, 2, 5, 7, 10, 13, 14, 26, 35, 65, 70, 91, 130, 182, 455, 910
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 347,949,985,910,642, is 1.
Now, the common factors can be found like this.
347:347
949:13x 73
985:5x 197
910:2x 5x 7x 13
642:2x 3x 107
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 13 = 130
Therefore, the value for common factors is 130.
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 = 189499617680100/(1x130)
LCM = 189499617680100/130
LCM = 1457689366770
Thus, we can understand that the LCM of 347,949,985,910,642 is 1457689366770.
