Given numbers are 977,956,420,572,184
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,956,420,572,184 is 645112748280.
Find LCM of 977,956,420,572,184 with Prime Factorization
| 2 | 977, 956, 420, 572, 184 |
| 2 | 977, 478, 210, 286, 92 |
| 977, 239, 105, 143, 46 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 977 x 239 x 105 x 143 x 46 = 645112748280
Therefore, the lowest common multiple of 977,956,420,572,184 is 645112748280.
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.
977 x 956 x 420 x 572 x 184 = 41287215889920
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.
977 : 1, 977
956 : 1, 2, 4, 239, 478, 956
420 : 1, 2, 3, 4, 5, 6, 7, 10, 12, 14, 15, 20, 21, 28, 30, 35, 42, 60, 70, 84, 105, 140, 210, 420
572 : 1, 2, 4, 11, 13, 22, 26, 44, 52, 143, 286, 572
184 : 1, 2, 4, 8, 23, 46, 92, 184
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,956,420,572,184, is 1.
Now, the common factors can be found like this.
977:977
956:2x 2x 239
420:2x 2x 3x 5x 7
572:2x 2x 11x 13
184:2x 2x 2x 23
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 2 = 64
Therefore, the value for common factors is 64.
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 = 41287215889920/(1x64)
LCM = 41287215889920/64
LCM = 645112748280
Thus, we can understand that the LCM of 977,956,420,572,184 is 645112748280.
