Given numbers are 977,865,992,506,615
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 977,865,992,506,615 is 26088431915040.
Find LCM of 977,865,992,506,615 with Prime Factorization
| 2 | 977, 865, 992, 506, 615 |
| 5 | 977, 865, 496, 253, 615 |
| 977, 173, 496, 253, 123 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 977 x 173 x 496 x 253 x 123 = 26088431915040
Therefore, the lowest common multiple of 977,865,992,506,615 is 26088431915040.
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.
977 x 865 x 992 x 506 x 615 = 260884319150400
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.
977 : 1, 977
865 : 1, 5, 173, 865
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
506 : 1, 2, 11, 22, 23, 46, 253, 506
615 : 1, 3, 5, 15, 41, 123, 205, 615
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 977,865,992,506,615, is 1.
Now, the common factors can be found like this.
977:977
865:5x 173
992:2x 2x 2x 2x 2x 31
506:2x 11x 23
615:3x 5x 41
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 5 = 10
Therefore, the value for common factors is 10.
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 = 260884319150400/(1x10)
LCM = 260884319150400/10
LCM = 26088431915040
Thus, we can understand that the LCM of 977,865,992,506,615 is 26088431915040.
