take the first three numbers and the remaining three numbers, they both have the same patern: 15+9=24 24+1=25 and 5+9=14 14+1=15now what relates both groups is the division of the last number of the 1st group by 5 to get the first number of the remaining three which is also 5 (check it)now repeating the same thing for 15 (the last of the second three) you will get 3 then 3+9=12 then 12+1=13
for three 3 6 9 12 for five 5 10 15 20 these both numbers dont share a common denominator in the first 4 multiples
They are: 14+15+16 = 45
the sum of the first 15 prime numbers is 328 .
The common factors are: 1, 5
15, 30 and 45 have a GCF of 15.
15, 30, 45
15, 30 and 45.
They are the first three odd prime numbers.
To find the third number, divide the product of the three numbers by the product of the two known numbers. First, calculate the product of the known numbers: 13 × 15 = 195. Then, divide 2730 by 195: 2730 ÷ 195 = 14. Therefore, the third number is 14.
