HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 945, 225 i.e. 45 the largest integer that leaves a remainder zero for all numbers.

HCF of 945, 225 is 45 the largest number which exactly divides all the numbers i.e. where the remainder is zero. Let us get into the working of this example.

Consider we have numbers 945, 225 and we need to find the HCF of these numbers. To do so, we need to choose the largest integer first and then as per Euclid's Division Lemma a = bq + r where 0 ≤ r ≤ b

Highest common factor (HCF) of 945, 225 is 45.

HCF(945, 225) = 45

HCF of 945, 225 using Euclid's algorithm

Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.

HCF of:

Highest common factor (HCF) of 945, 225 is 45.

Highest Common Factor of 945,225 using Euclid's algorithm

Highest Common Factor of 945,225 is 45

Step 1: Since 945 > 225, we apply the division lemma to 945 and 225, to get

945 = 225 x 4 + 45

Step 2: Since the reminder 225 ≠ 0, we apply division lemma to 45 and 225, to get

225 = 45 x 5 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 45, the HCF of 945 and 225 is 45

Notice that 45 = HCF(225,45) = HCF(945,225) .
