Given numbers are 972,278,940,646,541
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 972,278,940,646,541 is 5548156652340.
Find LCM of 972,278,940,646,541 with Prime Factorization
| 2 | 972, 278, 940, 646, 541 |
| 2 | 486, 139, 470, 323, 541 |
| 243, 139, 235, 323, 541 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 243 x 139 x 235 x 323 x 541 = 5548156652340
Therefore, the lowest common multiple of 972,278,940,646,541 is 5548156652340.
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.
972 x 278 x 940 x 646 x 541 = 88770506437440
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.
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
278 : 1, 2, 139, 278
940 : 1, 2, 4, 5, 10, 20, 47, 94, 188, 235, 470, 940
646 : 1, 2, 17, 19, 34, 38, 323, 646
541 : 1, 541
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 972,278,940,646,541, is 1.
Now, the common factors can be found like this.
972:2x 2x 3x 3x 3x 3x 3
278:2x 139
940:2x 2x 5x 47
646:2x 17x 19
541:541
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 2 = 16
Therefore, the value for common factors is 16.
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 = 88770506437440/(1x16)
LCM = 88770506437440/16
LCM = 5548156652340
Thus, we can understand that the LCM of 972,278,940,646,541 is 5548156652340.
