HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 949, 644, 225 i.e. 1 the largest integer that leaves a remainder zero for all numbers.

HCF of 949, 644, 225 is 1 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 949, 644, 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 949, 644, 225 is 1.

HCF(949, 644, 225) = 1

HCF of 949, 644, 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 949, 644, 225 is 1.

Highest Common Factor of 949,644,225 using Euclid's algorithm

Highest Common Factor of 949,644,225 is 1

Step 1: Since 949 > 644, we apply the division lemma to 949 and 644, to get

949 = 644 x 1 + 305

Step 2: Since the reminder 644 ≠ 0, we apply division lemma to 305 and 644, to get

644 = 305 x 2 + 34

Step 3: We consider the new divisor 305 and the new remainder 34, and apply the division lemma to get

305 = 34 x 8 + 33

We consider the new divisor 34 and the new remainder 33,and apply the division lemma to get

34 = 33 x 1 + 1

We consider the new divisor 33 and the new remainder 1,and apply the division lemma to get

33 = 1 x 33 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 949 and 644 is 1

Notice that 1 = HCF(33,1) = HCF(34,33) = HCF(305,34) = HCF(644,305) = HCF(949,644) .


We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma

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

225 = 1 x 225 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 225 is 1

Notice that 1 = HCF(225,1) .
