Given numbers are 714,135,342,761,691
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 714,135,342,761,691 is 321016259970.
Find LCM of 714,135,342,761,691 with Prime Factorization
| 2 | 714, 135, 342, 761, 691 |
| 3 | 357, 135, 171, 761, 691 |
| 3 | 119, 45, 57, 761, 691 |
| 119, 15, 19, 761, 691 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 3 x 119 x 15 x 19 x 761 x 691 = 321016259970
Therefore, the lowest common multiple of 714,135,342,761,691 is 321016259970.
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.
714 x 135 x 342 x 761 x 691 = 17334878038380
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.
714 : 1, 2, 3, 6, 7, 14, 17, 21, 34, 42, 51, 102, 119, 238, 357, 714
135 : 1, 3, 5, 9, 15, 27, 45, 135
342 : 1, 2, 3, 6, 9, 18, 19, 38, 57, 114, 171, 342
761 : 1, 761
691 : 1, 691
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 714,135,342,761,691, is 1.
Now, the common factors can be found like this.
714:2x 3x 7x 17
135:3x 3x 3x 5
342:2x 3x 3x 19
761:761
691:691
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 3 = 54
Therefore, the value for common factors is 54.
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 = 17334878038380/(1x54)
LCM = 17334878038380/54
LCM = 321016259970
Thus, we can understand that the LCM of 714,135,342,761,691 is 321016259970.
