Given numbers are 154,402,985,996,705
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 154,402,985,996,705 is 237880561380.
Find LCM of 154,402,985,996,705 with Prime Factorization
| 2 | 154, 402, 985, 996, 705 |
| 3 | 77, 201, 985, 498, 705 |
| 5 | 77, 67, 985, 166, 235 |
| 77, 67, 197, 166, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 77 x 67 x 197 x 166 x 47 = 237880561380
Therefore, the lowest common multiple of 154,402,985,996,705 is 237880561380.
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.
154 x 402 x 985 x 996 x 705 = 42818501048400
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.
154 : 1, 2, 7, 11, 14, 22, 77, 154
402 : 1, 2, 3, 6, 67, 134, 201, 402
985 : 1, 5, 197, 985
996 : 1, 2, 3, 4, 6, 12, 83, 166, 249, 332, 498, 996
705 : 1, 3, 5, 15, 47, 141, 235, 705
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 154,402,985,996,705, is 1.
Now, the common factors can be found like this.
154:2x 7x 11
402:2x 3x 67
985:5x 197
996:2x 2x 3x 83
705:3x 5x 47
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 3x 5 = 180
Therefore, the value for common factors is 180.
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 = 42818501048400/(1x180)
LCM = 42818501048400/180
LCM = 237880561380
Thus, we can understand that the LCM of 154,402,985,996,705 is 237880561380.
