Given numbers are 535,142,923,642
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 535,142,923,642 is 2962830.
Find LCM of 535,142,923,642 with Prime Factorization
| 2 | 535, 142, 923, 642 |
| 71 | 535, 71, 923, 321 |
| 107 | 535, 1, 13, 321 |
| 5, 1, 13, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 71 x 107 x 5 x 1 x 13 x 3 = 2962830
Therefore, the lowest common multiple of 535,142,923,642 is 2962830.
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.
535 x 142 x 923 x 642 = 45017239020
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.
535 : 1, 5, 107, 535
142 : 1, 2, 71, 142
923 : 1, 13, 71, 923
642 : 1, 2, 3, 6, 107, 214, 321, 642
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 535,142,923,642, is 1.
Now, the common factors can be found like this.
535:5x 107
142:2x 71
923:13x 71
642:2x 3x 107
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 71x 107 = 15194
Therefore, the value for common factors is 15194.
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 = 45017239020/(1x15194)
LCM = 45017239020/15194
LCM = 2962830
Thus, we can understand that the LCM of 535,142,923,642 is 2962830.
