WebIf you use the traditional method to find out the HCF by prime factorisation, you'll find that the HCF is 1. Substituting our values in the equation, you'll get the following equation: 13*27=1x, where x is our unknown value. 13*27=351, which is equal to the right hand side of our equation as the RHS was multiplied by 1. WebHCF of 90 and 120 is the divisor that we get when the remainder becomes 0 after doing long division repeatedly. Step 1: Divide 120 (larger number) by 90 (smaller number). Step 2: Since the remainder ≠ 0, we will divide the divisor of step 1 (90) by the remainder (30). Step 3: Repeat this process until the remainder = 0.
WebAdding the digits is just a test of divisibility and you could ONLY use the sum of the digits as a test of divisibility for 3. So when you add the digits of 125, you get 8 which shows that it is not divisible by 3. For 2, the test of divisibility is looking at the last digit.
