Given numbers are 780,535,970,145,458
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 780,535,970,145,458 is 53763012420.
Find LCM of 780,535,970,145,458 with Prime Factorization
| 2 | 780, 535, 970, 145, 458 |
| 5 | 390, 535, 485, 145, 229 |
| 78, 107, 97, 29, 229 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 78 x 107 x 97 x 29 x 229 = 53763012420
Therefore, the lowest common multiple of 780,535,970,145,458 is 53763012420.
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.
780 x 535 x 970 x 145 x 458 = 26881506210000
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.
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
535 : 1, 5, 107, 535
970 : 1, 2, 5, 10, 97, 194, 485, 970
145 : 1, 5, 29, 145
458 : 1, 2, 229, 458
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 780,535,970,145,458, is 1.
Now, the common factors can be found like this.
780:2x 2x 3x 5x 13
535:5x 107
970:2x 5x 97
145:5x 29
458:2x 229
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 5x 5 = 500
Therefore, the value for common factors is 500.
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 = 26881506210000/(1x500)
LCM = 26881506210000/500
LCM = 53763012420
Thus, we can understand that the LCM of 780,535,970,145,458 is 53763012420.
