Given numbers are 712,749,780,146

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

The LCM of 712,749,780,146 is 7591354680.

Find LCM of 712,749,780,146 with Prime Factorization

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

2 x 2 x 178 x 749 x 195 x 73 = 7591354680

Therefore, the lowest common multiple of 712,749,780,146 is 7591354680.

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.

712 x 749 x 780 x 146 = 60730837440

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.

712 : 1, 2, 4, 8, 89, 178, 356, 712

749 : 1, 7, 107, 749

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

146 : 1, 2, 73, 146

1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 712,749,780,146, is 1.

Now, the common factors can be found like this.

712:2x 2x 2x 89

749:7x 107

780:2x 2x 3x 5x 13

146:2x 73

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 2 = 8

Therefore, the value for common factors is 8.

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 = 60730837440/(1x8)

LCM = 60730837440/8

LCM = 7591354680

Thus, we can understand that the LCM of 712,749,780,146 is 7591354680.
