Given numbers are 709,942,195,628
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 709,942,195,628 is 86824140.
Find LCM of 709,942,195,628 with Prime Factorization
2 | 709, 942, 195, 628 |
3 | 709, 471, 195, 314 |
157 | 709, 157, 65, 314 |
709, 1, 65, 2 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 157 x 709 x 1 x 65 x 2 = 86824140
Therefore, the lowest common multiple of 709,942,195,628 is 86824140.
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.
709 x 942 x 195 x 628 = 81788339880
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.
709 : 1, 709
942 : 1, 2, 3, 6, 157, 314, 471, 942
195 : 1, 3, 5, 13, 15, 39, 65, 195
628 : 1, 2, 4, 157, 314, 628
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 709,942,195,628, is 1.
Now, the common factors can be found like this.
709:709
942:2x 3x 157
195:3x 5x 13
628:2x 2x 157
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 157 = 942
Therefore, the value for common factors is 942.
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 = 81788339880/(1x942)
LCM = 81788339880/942
LCM = 86824140
Thus, we can understand that the LCM of 709,942,195,628 is 86824140.
