Both of them are a multiple of 1
42 is a multiple of 3 because 14*3 = 42
The Least Common Multiple (LCM) for 40 19 is 760.
To calculate the number of neutrons in an atom of potassium-40, subtract the atomic number (which is 19 for potassium) from the mass number (which is 40 for potassium-40). So, 40 (mass number) - 19 (atomic number) = 21 neutrons in potassium-40.
The Least Common Multiple (LCM) for 19 40 37 11 is 309,320.
Nope :D Hope i helped :)
Any multiple of 19.
19 can be both the factor of another number and a multiple. For example, 19 is a multiple of 1 (1 x 19 = 19). This is the only example of where 19 is a multiple of an integer (as 19 is prime). An example of 19 being a factor is when looking at the number 38. 2x19=38, therefore 19 is a factor of 38. There are many numbers (infinitely many) which have 19 as a factor.
No. 19 is a prime number and is not a multiple of any number
40 5 x 8 = 40, so 40 is a multiple of both 5 and 8.
Any multiple of 40.
No. 580/40=14.5 (not a whole number, which is needed in order to indicate that it is a multiple)
40 Least Common Multiple for two numbers is a number that is divisible exactly by both of the 2 considered numbers. Since 40 here is a multiple of 5, 40 is the smallest number that is divisible by both 5 and 40.
