Given numbers are 770,781,165,496,603
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 770,781,165,496,603 is 8175570480.
Find LCM of 770,781,165,496,603 with Prime Factorization
| 2 | 770, 781, 165, 496, 603 |
| 3 | 385, 781, 165, 248, 603 |
| 5 | 385, 781, 55, 248, 201 |
| 11 | 77, 781, 11, 248, 201 |
| 7, 71, 1, 248, 201 |
Multiply the prime numbers at the bottom and the left side.
2 x 3 x 5 x 11 x 7 x 71 x 1 x 248 x 201 = 8175570480
Therefore, the lowest common multiple of 770,781,165,496,603 is 8175570480.
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.
770 x 781 x 165 x 496 x 603 = 29677320842400
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.
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
781 : 1, 11, 71, 781
165 : 1, 3, 5, 11, 15, 33, 55, 165
496 : 1, 2, 4, 8, 16, 31, 62, 124, 248, 496
603 : 1, 3, 9, 67, 201, 603
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,781,165,496,603, is 1.
Now, the common factors can be found like this.
770:2x 5x 7x 11
781:11x 71
165:3x 5x 11
496:2x 2x 2x 2x 31
603:3x 3x 67
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 11x 11 = 3630
Therefore, the value for common factors is 3630.
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 = 29677320842400/(1x3630)
LCM = 29677320842400/3630
LCM = 8175570480
Thus, we can understand that the LCM of 770,781,165,496,603 is 8175570480.
