Find LCM of 921,277,992,700,770 with Prime Factorization
2 | 921, 277, 992, 700, 770 |
2 | 921, 277, 496, 350, 385 |
5 | 921, 277, 248, 175, 385 |
7 | 921, 277, 248, 35, 77 |
921, 277, 248, 5, 11 |
Multiply the prime numbers at the bottom and the left side.
2 x 2 x 5 x 7 x 921 x 277 x 248 x 5 x 11 = 487171423200
Therefore, the lowest common multiple of 921,277,992,700,770 is 487171423200.
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.
921 x 277 x 992 x 700 x 770 = 136407998496000
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.
921 : 1, 3, 307, 921
277 : 1, 277
992 : 1, 2, 4, 8, 16, 31, 32, 62, 124, 248, 496, 992
700 : 1, 2, 4, 5, 7, 10, 14, 20, 25, 28, 35, 50, 70, 100, 140, 175, 350, 700
770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 921,277,992,700,770, is 1.
Now, the common factors can be found like this.
921:3x 307
277:277
992:2x 2x 2x 2x 2x 31
700:2x 2x 5x 5x 7
770:2x 5x 7x 11
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 2x 2x 5x 7 = 280
Therefore, the value for common factors is 280.
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 = 136407998496000/(1x280)
LCM = 136407998496000/280
LCM = 487171423200
Thus, we can understand that the LCM of 921,277,992,700,770 is 487171423200.
