Given numbers are 139,225,970,342
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 139,225,970,342 is 115279650.
Find LCM of 139,225,970,342 with Prime Factorization
| 2 | 139, 225, 970, 342 |
| 3 | 139, 225, 485, 171 |
| 3 | 139, 75, 485, 57 |
| 5 | 139, 25, 485, 19 |
| 139, 5, 97, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 5 x 139 x 5 x 97 x 19 = 115279650
Therefore, the lowest common multiple of 139,225,970,342 is 115279650.
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.
139 x 225 x 970 x 342 = 10375168500
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.
139 : 1, 139
225 : 1, 3, 5, 9, 15, 25, 45, 75, 225
970 : 1, 2, 5, 10, 97, 194, 485, 970
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 139,225,970,342, is 1.
Now, the common factors can be found like this.
139:139
225:3x 3x 5x 5
970:2x 5x 97
342:2x 3x 3x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 5 = 90
Therefore, the value for common factors is 90.
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 = 10375168500/(1x90)
LCM = 10375168500/90
LCM = 115279650
Thus, we can understand that the LCM of 139,225,970,342 is 115279650.
