Given numbers are 770,140,743,780,776

The least common multiple of numbers can be find using the prime factorization method or LCM formula.

The LCM of 770,140,743,780,776 is 8657168520.

Find LCM of 770,140,743,780,776 with Prime Factorization

Multiply the prime numbers at the bottom and the left side.

2 x 2 x 5 x 7 x 11 x 1 x 743 x 39 x 194 = 8657168520

Therefore, the lowest common multiple of 770,140,743,780,776 is 8657168520.

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.

770 x 140 x 743 x 780 x 776 = 48480143712000

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.

770 : 1, 2, 5, 7, 10, 11, 14, 22, 35, 55, 70, 77, 110, 154, 385, 770

140 : 1, 2, 4, 5, 7, 10, 14, 20, 28, 35, 70, 140

743 : 1, 743

780 : 1, 2, 3, 4, 5, 6, 10, 12, 13, 15, 20, 26, 30, 39, 52, 60, 65, 78, 130, 156, 195, 260, 390, 780

776 : 1, 2, 4, 8, 97, 194, 388, 776

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 770,140,743,780,776, is 1.

Now, the common factors can be found like this.

770:2x 5x 7x 11

140:2x 2x 5x 7

743:743

780:2x 2x 3x 5x 13

776:2x 2x 2x 97

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 2x 2x 5x 5x 7 = 5600

Therefore, the value for common factors is 5600.

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 = 48480143712000/(1x5600)

LCM = 48480143712000/5600

LCM = 8657168520

Thus, we can understand that the LCM of 770,140,743,780,776 is 8657168520.
