Given numbers are 528,150,221,445,765
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 528,150,221,445,765 is 778892400.
Find LCM of 528,150,221,445,765 with Prime Factorization
| 2 | 528, 150, 221, 445, 765 |
| 3 | 264, 75, 221, 445, 765 |
| 5 | 88, 25, 221, 445, 255 |
| 17 | 88, 5, 221, 89, 51 |
| 88, 5, 13, 89, 3 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 17 x 88 x 5 x 13 x 89 x 3 = 778892400
Therefore, the lowest common multiple of 528,150,221,445,765 is 778892400.
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.
528 x 150 x 221 x 445 x 765 = 5958526860000
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.
528 : 1, 2, 3, 4, 6, 8, 11, 12, 16, 22, 24, 33, 44, 48, 66, 88, 132, 176, 264, 528
150 : 1, 2, 3, 5, 6, 10, 15, 25, 30, 50, 75, 150
221 : 1, 13, 17, 221
445 : 1, 5, 89, 445
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 528,150,221,445,765, is 1.
Now, the common factors can be found like this.
528:2x 2x 2x 2x 3x 11
150:2x 3x 5x 5
221:13x 17
445:5x 89
765:3x 3x 5x 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 3x 3x 5x 5x 17 = 7650
Therefore, the value for common factors is 7650.
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 = 5958526860000/(1x7650)
LCM = 5958526860000/7650
LCM = 778892400
Thus, we can understand that the LCM of 528,150,221,445,765 is 778892400.
