The answer is 45 135=3x3x3x5 315=3x3x5x7 each number has at least 2 3s and one 5 3x3x5=45 Your welcome
What is the factors of numbers 45 and 42?
45=3x3x5. 42=2x3x7 1, 2, 3, 6, 7, 14, 21, 42 1, 3, 5, 9, 15, 45
What is the HCF of 60 and 45?
To find the HCF of two numbers you first need to express them as the product of their prime factors. In this case you'd get: 45 = 3x3x5 60 = 2x2x3x5 The next step is to identify any common prime factors. In this case both numbers have a 3 and a 5 as a prime factor. Multiplying these together gives: 3x5 = 15 And so 15 is the HCF of 45 and 60.
What is HCF and LCM of 30 and 45?
To find the HCF you first need to break the numbers down into their prime factors. In this case we have: 30 = 2x3x5 45 = 3x3x5 The next step is to identify any common factors. In this case both numbers have 3 and 5 as prime factors. To find the HCF, multiply these together: 3x5 = 15. To get the LCM, multiply the numbers together then divide by the HCF: 30x45/15 = 90.
What is the greatest factor of 45 and 60?
To find the GCF of two numbers, you first split them both into their prime factors. 45 = 3x3x5 60 = 2x2x3x5 The next step is to find the common prime factors. In this case, both numbers have one 3 as a factor, and both have one 5 as a factor. To get the greatest common factor, we find the product of these common prime factors: 5x3=15 Thus the greatest common factor of 45 and 60 is 15.
