Given numbers are 101,791,480,420
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 101,791,480,420 is 38347680.
Find LCM of 101,791,480,420 with Prime Factorization
| 2 | 101, 791, 480, 420 |
| 2 | 101, 791, 240, 210 |
| 3 | 101, 791, 120, 105 |
| 5 | 101, 791, 40, 35 |
| 7 | 101, 791, 8, 7 |
| 101, 113, 8, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 7 x 101 x 113 x 8 x 1 = 38347680
Therefore, the lowest common multiple of 101,791,480,420 is 38347680.
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.
101 x 791 x 480 x 420 = 16106025600
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.
101 : 1, 101
791 : 1, 7, 113, 791
480 : 1, 2, 3, 4, 5, 6, 8, 10, 12, 15, 16, 20, 24, 30, 32, 40, 48, 60, 80, 96, 120, 160, 240, 480
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 101,791,480,420, is 1.
Now, the common factors can be found like this.
101:101
791:7x 113
480:2x 2x 2x 2x 2x 3x 5
420:2x 2x 3x 5x 7
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 3x 5x 7 = 420
Therefore, the value for common factors is 420.
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 = 16106025600/(1x420)
LCM = 16106025600/420
LCM = 38347680
Thus, we can understand that the LCM of 101,791,480,420 is 38347680.
