Given numbers are 428,140,525,829
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 428,140,525,829 is 186276300.
Find LCM of 428,140,525,829 with Prime Factorization
2 | 428, 140, 525, 829 |
2 | 214, 70, 525, 829 |
5 | 107, 35, 525, 829 |
7 | 107, 7, 105, 829 |
107, 1, 15, 829 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 107 x 1 x 15 x 829 = 186276300
Therefore, the lowest common multiple of 428,140,525,829 is 186276300.
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.
428 x 140 x 525 x 829 = 26078682000
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.
428 : 1, 2, 4, 107, 214, 428
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
525 : 1, 3, 5, 7, 15, 21, 25, 35, 75, 105, 175, 525
829 : 1, 829
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,140,525,829, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
140:2x 2x 5x 7
525:3x 5x 5x 7
829:829
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 5x 7 = 140
Therefore, the value for common factors is 140.
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 = 26078682000/(1x140)
LCM = 26078682000/140
LCM = 186276300
Thus, we can understand that the LCM of 428,140,525,829 is 186276300.
