Given numbers are 735,714,687,278
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 735,714,687,278 is 795456690.
Find LCM of 735,714,687,278 with Prime Factorization
| 2 | 735, 714, 687, 278 |
| 3 | 735, 357, 687, 139 |
| 7 | 245, 119, 229, 139 |
| 35, 17, 229, 139 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 7 x 35 x 17 x 229 x 139 = 795456690
Therefore, the lowest common multiple of 735,714,687,278 is 795456690.
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.
735 x 714 x 687 x 278 = 100227542940
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.
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
687 : 1, 3, 229, 687
278 : 1, 2, 139, 278
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 735,714,687,278, is 1.
Now, the common factors can be found like this.
735:3x 5x 7x 7
714:2x 3x 7x 17
687:3x 229
278:2x 139
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 3x 3x 7 = 126
Therefore, the value for common factors is 126.
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 = 100227542940/(1x126)
LCM = 100227542940/126
LCM = 795456690
Thus, we can understand that the LCM of 735,714,687,278 is 795456690.
