HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 830, 965, 945 i.e. 5 the largest integer that leaves a remainder zero for all numbers.

HCF of 830, 965, 945 is 5 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 830, 965, 945 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 830, 965, 945 is 5.

HCF(830, 965, 945) = 5

HCF of 830, 965, 945 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 830, 965, 945 is 5.

Highest Common Factor of 830,965,945 using Euclid's algorithm

Highest Common Factor of 830,965,945 is 5

Step 1: Since 965 > 830, we apply the division lemma to 965 and 830, to get

965 = 830 x 1 + 135

Step 2: Since the reminder 830 ≠ 0, we apply division lemma to 135 and 830, to get

830 = 135 x 6 + 20

Step 3: We consider the new divisor 135 and the new remainder 20, and apply the division lemma to get

135 = 20 x 6 + 15

We consider the new divisor 20 and the new remainder 15,and apply the division lemma to get

20 = 15 x 1 + 5

We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get

15 = 5 x 3 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 830 and 965 is 5

Notice that 5 = HCF(15,5) = HCF(20,15) = HCF(135,20) = HCF(830,135) = HCF(965,830) .


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

Step 1: Since 945 > 5, we apply the division lemma to 945 and 5, to get

945 = 5 x 189 + 0

The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 5 and 945 is 5

Notice that 5 = HCF(945,5) .
