Find LCM of 428,321,719,369,748 with Prime Factorization
| 2 | 428, 321, 719, 369, 748 |
| 2 | 214, 321, 719, 369, 374 |
| 3 | 107, 321, 719, 369, 187 |
| 107 | 107, 107, 719, 123, 187 |
| 1, 1, 719, 123, 187 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 107 x 1 x 1 x 719 x 123 x 187 = 21234431196
Therefore, the lowest common multiple of 428,321,719,369,748 is 21234431196.
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 321 x 719 x 369 x 748 = 27265009655664
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
321 : 1, 3, 107, 321
719 : 1, 719
369 : 1, 3, 9, 41, 123, 369
748 : 1, 2, 4, 11, 17, 22, 34, 44, 68, 187, 374, 748
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 428,321,719,369,748, is 1.
Now, the common factors can be found like this.
428:2x 2x 107
321:3x 107
719:719
369:3x 3x 41
748:2x 2x 11x 17
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 107 = 1284
Therefore, the value for common factors is 1284.
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 = 27265009655664/(1x1284)
LCM = 27265009655664/1284
LCM = 21234431196
Thus, we can understand that the LCM of 428,321,719,369,748 is 21234431196.
