Given numbers are 180,508,780,724,778
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 180,508,780,724,778 is 20924146620.
Find LCM of 180,508,780,724,778 with Prime Factorization
| 2 | 180, 508, 780, 724, 778 |
| 2 | 90, 254, 390, 362, 389 |
| 3 | 45, 127, 195, 181, 389 |
| 5 | 15, 127, 65, 181, 389 |
| 3, 127, 13, 181, 389 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 5 x 3 x 127 x 13 x 181 x 389 = 20924146620
Therefore, the lowest common multiple of 180,508,780,724,778 is 20924146620.
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.
180 x 508 x 780 x 724 x 778 = 40174361510400
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.
180 : 1, 2, 3, 4, 5, 6, 9, 10, 12, 15, 18, 20, 30, 36, 45, 60, 90, 180
508 : 1, 2, 4, 127, 254, 508
780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780
724 : 1, 2, 4, 181, 362, 724
778 : 1, 2, 389, 778
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 180,508,780,724,778, is 2.
Now, the common factors can be found like this.
180:2x 2x 3x 3x 5
508:2x 2x 127
780:2x 2x 3x 5x 13
724:2x 2x 181
778:2x 389
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 2x 2x 2x 2x 3x 5 = 960
Therefore, the value for common factors is 960.
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 = 40174361510400/(2x960)
LCM = 40174361510400/1920
LCM = 20924146620
Thus, we can understand that the LCM of 180,508,780,724,778 is 20924146620.
