Given numbers are 739,450,973,620,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 739,450,973,620,278 is 20061411300.
Find LCM of 739,450,973,620,278 with Prime Factorization
| 2 | 739, 450, 973, 620, 278 |
| 5 | 739, 225, 973, 310, 139 |
| 139 | 739, 45, 973, 62, 139 |
| 739, 45, 7, 62, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 139 x 739 x 45 x 7 x 62 x 1 = 20061411300
Therefore, the lowest common multiple of 739,450,973,620,278 is 20061411300.
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.
739 x 450 x 973 x 620 x 278 = 55770723414000
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.
739 : 1, 739
450 : 1, 2, 3, 5, 6, 9, 10, 15, 18, 25, 30, 45, 50, 75, 90, 150, 225, 450
973 : 1, 7, 139, 973
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 739,450,973,620,278, is 1.
Now, the common factors can be found like this.
739:739
450:2x 3x 3x 5x 5
973:7x 139
620:2x 2x 5x 31
278:2x 139
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 139 = 2780
Therefore, the value for common factors is 2780.
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 = 55770723414000/(1x2780)
LCM = 55770723414000/2780
LCM = 20061411300
Thus, we can understand that the LCM of 739,450,973,620,278 is 20061411300.
