Given numbers are 974,893,342,135
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 974,893,342,135 is 117420570.
Find LCM of 974,893,342,135 with Prime Factorization
| 2 | 974, 893, 342, 135 |
| 3 | 487, 893, 171, 135 |
| 3 | 487, 893, 57, 45 |
| 19 | 487, 893, 19, 15 |
| 487, 47, 1, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 19 x 487 x 47 x 1 x 15 = 117420570
Therefore, the lowest common multiple of 974,893,342,135 is 117420570.
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.
974 x 893 x 342 x 135 = 40157834940
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.
974 : 1, 2, 487, 974
893 : 1, 19, 47, 893
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
135 : 1, 3, 5, 9, 15, 27, 45, 135
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 974,893,342,135, is 1.
Now, the common factors can be found like this.
974:2x 487
893:19x 47
342:2x 3x 3x 19
135:3x 3x 3x 5
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 19 = 342
Therefore, the value for common factors is 342.
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 = 40157834940/(1x342)
LCM = 40157834940/342
LCM = 117420570
Thus, we can understand that the LCM of 974,893,342,135 is 117420570.
