Given numbers are 980,624,791,617
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 980,624,791,617 is 10658946480.
Find LCM of 980,624,791,617 with Prime Factorization
| 2 | 980, 624, 791, 617 |
| 2 | 490, 312, 791, 617 |
| 7 | 245, 156, 791, 617 |
| 35, 156, 113, 617 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 7 x 35 x 156 x 113 x 617 = 10658946480
Therefore, the lowest common multiple of 980,624,791,617 is 10658946480.
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.
980 x 624 x 791 x 617 = 298450501440
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.
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
624 : 1, 2, 3, 4, 6, 8, 12, 13, 16, 24, 26, 39, 48, 52, 78, 104, 156, 208, 312, 624
791 : 1, 7, 113, 791
617 : 1, 617
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 980,624,791,617, is 1.
Now, the common factors can be found like this.
980:2x 2x 5x 7x 7
624:2x 2x 2x 2x 3x 13
791:7x 113
617:617
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 7 = 28
Therefore, the value for common factors is 28.
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 = 298450501440/(1x28)
LCM = 298450501440/28
LCM = 10658946480
Thus, we can understand that the LCM of 980,624,791,617 is 10658946480.
