Given numbers are 782,254,918,434,767
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 782,254,918,434,767 is 446302516842.
Find LCM of 782,254,918,434,767 with Prime Factorization
| 2 | 782, 254, 918, 434, 767 |
| 17 | 391, 127, 459, 217, 767 |
| 23, 127, 27, 217, 767 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 23 x 127 x 27 x 217 x 767 = 446302516842
Therefore, the lowest common multiple of 782,254,918,434,767 is 446302516842.
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.
782 x 254 x 918 x 434 x 767 = 60697142290512
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.
782 : 1, 2, 17, 23, 34, 46, 391, 782
254 : 1, 2, 127, 254
918 : 1, 2, 3, 6, 9, 17, 18, 27, 34, 51, 54, 102, 153, 306, 459, 918
434 : 1, 2, 7, 14, 31, 62, 217, 434
767 : 1, 13, 59, 767
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 782,254,918,434,767, is 1.
Now, the common factors can be found like this.
782:2x 17x 23
254:2x 127
918:2x 3x 3x 3x 17
434:2x 7x 31
767:13x 59
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 17 = 136
Therefore, the value for common factors is 136.
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 = 60697142290512/(1x136)
LCM = 60697142290512/136
LCM = 446302516842
Thus, we can understand that the LCM of 782,254,918,434,767 is 446302516842.
