Given numbers are 778,931,475,756
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 778,931,475,756 is 977829300.
Find LCM of 778,931,475,756 with Prime Factorization
2 | 778, 931, 475, 756 |
7 | 389, 931, 475, 378 |
19 | 389, 133, 475, 54 |
389, 7, 25, 54 |
Multiply the prime numbers at the bottom and the left side.
2 x 7 x 19 x 389 x 7 x 25 x 54 = 977829300
Therefore, the lowest common multiple of 778,931,475,756 is 977829300.
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.
778 x 931 x 475 x 756 = 260102593800
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.
778 : 1, 2, 389, 778
931 : 1, 7, 19, 49, 133, 931
475 : 1, 5, 19, 25, 95, 475
756 : 1, 2, 3, 4, 6, 7, 9, 12, 14, 18, 21, 27, 28, 36, 42, 54, 63, 84, 108, 126, 189, 252, 378, 756
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 778,931,475,756, is 1.
Now, the common factors can be found like this.
778:2x 389
931:7x 7x 19
475:5x 5x 19
756:2x 2x 3x 3x 3x 7
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
2x 7x 19 = 266
Therefore, the value for common factors is 266.
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 = 260102593800/(1x266)
LCM = 260102593800/266
LCM = 977829300
Thus, we can understand that the LCM of 778,931,475,756 is 977829300.
