Given numbers are 430,156,695,247
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 430,156,695,247 is 88579140.
Find LCM of 430,156,695,247 with Prime Factorization
| 2 | 430, 156, 695, 247 |
| 5 | 215, 78, 695, 247 |
| 13 | 43, 78, 139, 247 |
| 43, 6, 139, 19 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 13 x 43 x 6 x 139 x 19 = 88579140
Therefore, the lowest common multiple of 430,156,695,247 is 88579140.
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.
430 x 156 x 695 x 247 = 11515288200
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.
430 : 1, 2, 5, 10, 43, 86, 215, 430
156 : 1, 2, 3, 4, 6, 12, 13, 26, 39, 52, 78, 156
695 : 1, 5, 139, 695
247 : 1, 13, 19, 247
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 430,156,695,247, is 1.
Now, the common factors can be found like this.
430:2x 5x 43
156:2x 2x 3x 13
695:5x 139
247:13x 19
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 13 = 130
Therefore, the value for common factors is 130.
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 = 11515288200/(1x130)
LCM = 11515288200/130
LCM = 88579140
Thus, we can understand that the LCM of 430,156,695,247 is 88579140.
