Given numbers are 705,163,140,154,757
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 705,163,140,154,757 is 26793121740.
Find LCM of 705,163,140,154,757 with Prime Factorization
| 2 | 705, 163, 140, 154, 757 |
| 5 | 705, 163, 70, 77, 757 |
| 7 | 141, 163, 14, 77, 757 |
| 141, 163, 2, 11, 757 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 141 x 163 x 2 x 11 x 757 = 26793121740
Therefore, the lowest common multiple of 705,163,140,154,757 is 26793121740.
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.
705 x 163 x 140 x 154 x 757 = 1875518521800
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.
705 : 1, 3, 5, 15, 47, 141, 235, 705
163 : 1, 163
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
154 : 1, 2, 7, 11, 14, 22, 77, 154
757 : 1, 757
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 705,163,140,154,757, is 1.
Now, the common factors can be found like this.
705:3x 5x 47
163:163
140:2x 2x 5x 7
154:2x 7x 11
757:757
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5x 7 = 70
Therefore, the value for common factors is 70.
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 = 1875518521800/(1x70)
LCM = 1875518521800/70
LCM = 26793121740
Thus, we can understand that the LCM of 705,163,140,154,757 is 26793121740.
