Given numbers are 971,140,765,323,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 971,140,765,323,615 is 16202280780.
Find LCM of 971,140,765,323,615 with Prime Factorization
| 3 | 971, 140, 765, 323, 615 |
| 5 | 971, 140, 255, 323, 205 |
| 17 | 971, 28, 51, 323, 41 |
| 971, 28, 3, 19, 41 |
Multiply the prime numbers at the bottom and the left side.
3 x 5 x 17 x 971 x 28 x 3 x 19 x 41 = 16202280780
Therefore, the lowest common multiple of 971,140,765,323,615 is 16202280780.
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.
971 x 140 x 765 x 323 x 615 = 20657907994500
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.
971 : 1, 971
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
765 : 1, 3, 5, 9, 15, 17, 45, 51, 85, 153, 255, 765
323 : 1, 17, 19, 323
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 971,140,765,323,615, is 1.
Now, the common factors can be found like this.
971:971
140:2x 2x 5x 7
765:3x 3x 5x 17
323:17x 19
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 5x 5x 17 = 1275
Therefore, the value for common factors is 1275.
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 = 20657907994500/(1x1275)
LCM = 20657907994500/1275
LCM = 16202280780
Thus, we can understand that the LCM of 971,140,765,323,615 is 16202280780.
