Use the digits 1,2,3,4, and 5 two two-digit and three digit number so that their product is the least possible. Use each digit only once.
431*52 = 22412
To find the two two-digit and three-digit numbers using the digits 1, 2, 3, 4, and 5 with their product being the least possible, we can follow these steps:
Step 1: Arrange the digits in ascending order from left to right. In this case, it will be 1, 2, 3, 4, 5.
Step 2: Use the first two digits to form the first two-digit number. In this case, it will be 12.
Step 3: Use the remaining three digits to form the three-digit number. In this case, it will be 345.
Step 4: Multiply the two numbers obtained in Step 2 and Step 3. 12 multiplied by 345 equals 4140.
Therefore, the two two-digit and three-digit numbers using the digits 1, 2, 3, 4, and 5, with their product being the least possible, are 12 and 345, and their product is 4140.
