Find LCM of 961,174,735,140,661 with Prime Factorization
| 2 | 961, 174, 735, 140, 661 |
| 3 | 961, 87, 735, 70, 661 |
| 5 | 961, 29, 245, 70, 661 |
| 7 | 961, 29, 49, 14, 661 |
| 961, 29, 7, 2, 661 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 7 x 961 x 29 x 7 x 2 x 661 = 54158942460
Therefore, the lowest common multiple of 961,174,735,140,661 is 54158942460.
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.
961 x 174 x 735 x 140 x 661 = 11373377916600
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.
961 : 1, 31, 961
174 : 1, 2, 3, 6, 29, 58, 87, 174
735 : 1, 3, 5, 7, 15, 21, 35, 49, 105, 147, 245, 735
140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140
661 : 1, 661
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 961,174,735,140,661, is 1.
Now, the common factors can be found like this.
961:31x 31
174:2x 3x 29
735:3x 5x 7x 7
140:2x 2x 5x 7
661:661
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 5x 7 = 210
Therefore, the value for common factors is 210.
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 = 11373377916600/(1x210)
LCM = 11373377916600/210
LCM = 54158942460
Thus, we can understand that the LCM of 961,174,735,140,661 is 54158942460.
