Given numbers are 272,972,218,654
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 272,972,218,654 is 7204464.
Find LCM of 272,972,218,654 with Prime Factorization
| 2 | 272, 972, 218, 654 |
| 2 | 136, 486, 109, 327 |
| 3 | 68, 243, 109, 327 |
| 109 | 68, 81, 109, 109 |
| 68, 81, 1, 1 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 3 x 109 x 68 x 81 x 1 x 1 = 7204464
Therefore, the lowest common multiple of 272,972,218,654 is 7204464.
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.
272 x 972 x 218 x 654 = 37693755648
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.
272 : 1, 2, 4, 8, 16, 17, 34, 68, 136, 272
972 : 1, 2, 3, 4, 6, 9, 12, 18, 27, 36, 54, 81, 108, 162, 243, 324, 486, 972
218 : 1, 2, 109, 218
654 : 1, 2, 3, 6, 109, 218, 327, 654
2 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 272,972,218,654, is 2.
Now, the common factors can be found like this.
272:2x 2x 2x 2x 17
972:2x 2x 3x 3x 3x 3x 3
218:2x 109
654:2x 3x 109
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 3x 109 = 2616
Therefore, the value for common factors is 2616.
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 = 37693755648/(2x2616)
LCM = 37693755648/5232
LCM = 7204464
Thus, we can understand that the LCM of 272,972,218,654 is 7204464.
