Given numbers are 639,178,304,803,356
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 639,178,304,803,356 is 13882893552.
Find LCM of 639,178,304,803,356 with Prime Factorization
| 2 | 639, 178, 304, 803, 356 |
| 2 | 639, 89, 152, 803, 178 |
| 89 | 639, 89, 76, 803, 89 |
| 639, 1, 76, 803, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 89 x 639 x 1 x 76 x 803 x 1 = 13882893552
Therefore, the lowest common multiple of 639,178,304,803,356 is 13882893552.
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.
639 x 178 x 304 x 803 x 356 = 9884620209024
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.
639 : 1, 3, 9, 71, 213, 639
178 : 1, 2, 89, 178
304 : 1, 2, 4, 8, 16, 19, 38, 76, 152, 304
803 : 1, 11, 73, 803
356 : 1, 2, 4, 89, 178, 356
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 639,178,304,803,356, is 1.
Now, the common factors can be found like this.
639:3x 3x 71
178:2x 89
304:2x 2x 2x 2x 19
803:11x 73
356:2x 2x 89
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 2x 89 = 712
Therefore, the value for common factors is 712.
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 = 9884620209024/(1x712)
LCM = 9884620209024/712
LCM = 13882893552
Thus, we can understand that the LCM of 639,178,304,803,356 is 13882893552.
