Given numbers are 710,968,639,188
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 710,968,639,188 is 145359720.
Find LCM of 710,968,639,188 with Prime Factorization
| 2 | 710, 968, 639, 188 |
| 2 | 355, 484, 639, 94 |
| 71 | 355, 242, 639, 47 |
| 5, 242, 9, 47 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 71 x 5 x 242 x 9 x 47 = 145359720
Therefore, the lowest common multiple of 710,968,639,188 is 145359720.
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.
710 x 968 x 639 x 188 = 82564320960
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.
710 : 1, 2, 5, 10, 71, 142, 355, 710
968 : 1, 2, 4, 8, 11, 22, 44, 88, 121, 242, 484, 968
639 : 1, 3, 9, 71, 213, 639
188 : 1, 2, 4, 47, 94, 188
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 710,968,639,188, is 1.
Now, the common factors can be found like this.
710:2x 5x 71
968:2x 2x 2x 11x 11
639:3x 3x 71
188:2x 2x 47
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 71 = 568
Therefore, the value for common factors is 568.
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 = 82564320960/(1x568)
LCM = 82564320960/568
LCM = 145359720
Thus, we can understand that the LCM of 710,968,639,188 is 145359720.
