Given numbers are 671,777,761,507,378
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 671,777,761,507,378 is 1206944793054.
Find LCM of 671,777,761,507,378 with Prime Factorization
| 3 | 671, 777, 761, 507, 378 |
| 7 | 671, 259, 761, 169, 126 |
| 671, 37, 761, 169, 18 |
Multiply the prime numbers at the bottom and the left side.
3 x 7 x 671 x 37 x 761 x 169 x 18 = 1206944793054
Therefore, the lowest common multiple of 671,777,761,507,378 is 1206944793054.
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.
671 x 777 x 761 x 507 x 378 = 76037521962402
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.
671 : 1, 11, 61, 671
777 : 1, 3, 7, 21, 37, 111, 259, 777
761 : 1, 761
507 : 1, 3, 13, 39, 169, 507
378 : 1, 2, 3, 6, 7, 9, 14, 18, 21, 27, 42, 54, 63, 126, 189, 378
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 671,777,761,507,378, is 1.
Now, the common factors can be found like this.
671:11x 61
777:3x 7x 37
761:761
507:3x 13x 13
378:2x 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.
3x 3x 7 = 63
Therefore, the value for common factors is 63.
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 = 76037521962402/(1x63)
LCM = 76037521962402/63
LCM = 1206944793054
Thus, we can understand that the LCM of 671,777,761,507,378 is 1206944793054.
