Given numbers are 973,694,980,915,961
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 973,694,980,915,961 is 8312752077420.
Find LCM of 973,694,980,915,961 with Prime Factorization
| 2 | 973, 694, 980, 915, 961 |
| 5 | 973, 347, 490, 915, 961 |
| 7 | 973, 347, 98, 183, 961 |
| 139, 347, 14, 183, 961 |
Multiply the prime numbers at the bottom and the left side.
2 x 5 x 7 x 139 x 347 x 14 x 183 x 961 = 8312752077420
Therefore, the lowest common multiple of 973,694,980,915,961 is 8312752077420.
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.
973 x 694 x 980 x 915 x 961 = 581892645419400
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.
973 : 1, 7, 139, 973
694 : 1, 2, 347, 694
980 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 49, 70, 98, 140, 196, 245, 490, 980
915 : 1, 3, 5, 15, 61, 183, 305, 915
961 : 1, 31, 961
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 973,694,980,915,961, is 1.
Now, the common factors can be found like this.
973:7x 139
694:2x 347
980:2x 2x 5x 7x 7
915:3x 5x 61
961:31x 31
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 = 581892645419400/(1x70)
LCM = 581892645419400/70
LCM = 8312752077420
Thus, we can understand that the LCM of 973,694,980,915,961 is 8312752077420.
