Given numbers are 973,782,137,663,620
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,782,137,663,620 is 1260278308380.
Find LCM of 973,782,137,663,620 with Prime Factorization
| 2 | 973, 782, 137, 663, 620 |
| 17 | 973, 391, 137, 663, 310 |
| 973, 23, 137, 39, 310 |
Multiply the prime numbers at the bottom and the left side.
2 x 17 x 973 x 23 x 137 x 39 x 310 = 1260278308380
Therefore, the lowest common multiple of 973,782,137,663,620 is 1260278308380.
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.
973 x 782 x 137 x 663 x 620 = 42849462484920
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.
973 : 1, 7, 139, 973
782 : 1, 2, 17, 23, 34, 46, 391, 782
137 : 1, 137
663 : 1, 3, 13, 17, 39, 51, 221, 663
620 : 1, 2, 4, 5, 10, 20, 31, 62, 124, 155, 310, 620
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,782,137,663,620, is 1.
Now, the common factors can be found like this.
973:7x 139
782:2x 17x 23
137:137
663:3x 13x 17
620:2x 2x 5x 31
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 = 42849462484920/(1x34)
LCM = 42849462484920/34
LCM = 1260278308380
Thus, we can understand that the LCM of 973,782,137,663,620 is 1260278308380.
