Given numbers are 962,947,416,644,780
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 962,947,416,644,780 is 35201580960.
Find LCM of 962,947,416,644,780 with Prime Factorization
| 2 | 962, 947, 416, 644, 780 |
| 2 | 481, 947, 208, 322, 390 |
| 13 | 481, 947, 104, 161, 195 |
| 37, 947, 8, 161, 15 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 13 x 37 x 947 x 8 x 161 x 15 = 35201580960
Therefore, the lowest common multiple of 962,947,416,644,780 is 35201580960.
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.
962 x 947 x 416 x 644 x 780 = 190370149831680
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.
962 : 1, 2, 13, 26, 37, 74, 481, 962
947 : 1, 947
416 : 1, 2, 4, 8, 13, 16, 26, 32, 52, 104, 208, 416
644 : 1, 2, 4, 7, 14, 23, 28, 46, 92, 161, 322, 644
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
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 962,947,416,644,780, is 1.
Now, the common factors can be found like this.
962:2x 13x 37
947:947
416:2x 2x 2x 2x 2x 13
644:2x 2x 7x 23
780:2x 2x 3x 5x 13
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 2x 2x 13x 13 = 5408
Therefore, the value for common factors is 5408.
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 = 190370149831680/(1x5408)
LCM = 190370149831680/5408
LCM = 35201580960
Thus, we can understand that the LCM of 962,947,416,644,780 is 35201580960.
