Given numbers are 647,578,697,746
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 647,578,697,746 is 5719062038.
Find LCM of 647,578,697,746 with Prime Factorization
| 2 | 647, 578, 697, 746 |
| 17 | 647, 289, 697, 373 |
| 647, 17, 41, 373 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 647 x 17 x 41 x 373 = 5719062038
Therefore, the lowest common multiple of 647,578,697,746 is 5719062038.
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.
647 x 578 x 697 x 746 = 194448109292
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.
647 : 1, 647
578 : 1, 2, 17, 34, 289, 578
697 : 1, 17, 41, 697
746 : 1, 2, 373, 746
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 647,578,697,746, is 1.
Now, the common factors can be found like this.
647:647
578:2x 17x 17
697:17x 41
746:2x 373
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 17 = 34
Therefore, the value for common factors is 34.
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 = 194448109292/(1x34)
LCM = 194448109292/34
LCM = 5719062038
Thus, we can understand that the LCM of 647,578,697,746 is 5719062038.
