Given numbers are 650,870,749,778,655
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 650,870,749,778,655 is 2158416856050.
Find LCM of 650,870,749,778,655 with Prime Factorization
| 2 | 650, 870, 749, 778, 655 |
| 5 | 325, 435, 749, 389, 655 |
| 65, 87, 749, 389, 131 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 65 x 87 x 749 x 389 x 131 = 2158416856050
Therefore, the lowest common multiple of 650,870,749,778,655 is 2158416856050.
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.
650 x 870 x 749 x 778 x 655 = 215841685605000
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.
650 : 1, 2, 5, 10, 13, 25, 26, 50, 65, 130, 325, 650
870 : 1, 2, 3, 5, 6, 10, 15, 29, 30, 58, 87, 145, 174, 290, 435, 870
749 : 1, 7, 107, 749
778 : 1, 2, 389, 778
655 : 1, 5, 131, 655
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 650,870,749,778,655, is 1.
Now, the common factors can be found like this.
650:2x 5x 5x 13
870:2x 3x 5x 29
749:7x 107
778:2x 389
655:5x 131
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 5 = 100
Therefore, the value for common factors is 100.
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 = 215841685605000/(1x100)
LCM = 215841685605000/100
LCM = 2158416856050
Thus, we can understand that the LCM of 650,870,749,778,655 is 2158416856050.
