Given numbers are 137,972,697,340
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 137,972,697,340 is 464076540.
Find LCM of 137,972,697,340 with Prime Factorization
| 2 | 137, 972, 697, 340 |
| 2 | 137, 486, 697, 170 |
| 17 | 137, 243, 697, 85 |
| 137, 243, 41, 5 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 17 x 137 x 243 x 41 x 5 = 464076540
Therefore, the lowest common multiple of 137,972,697,340 is 464076540.
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.
137 x 972 x 697 x 340 = 31557204720
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.
137 : 1, 137
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
697 : 1, 17, 41, 697
340 : 1, 2, 4, 5, 10, 17, 20, 34, 68, 85, 170, 340
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 137,972,697,340, is 1.
Now, the common factors can be found like this.
137:137
972:2x 2x 3x 3x 3x 3x 3
697:17x 41
340:2x 2x 5x 17
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 17 = 68
Therefore, the value for common factors is 68.
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 = 31557204720/(1x68)
LCM = 31557204720/68
LCM = 464076540
Thus, we can understand that the LCM of 137,972,697,340 is 464076540.
