HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 964, 920, 971 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 964, 920, 971 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 964, 920, 971 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 964, 920, 971 is 1.
HCF(964, 920, 971) = 1
HCF of 964, 920, 971 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 964, 920, 971 is 1.
Highest Common Factor of 964,920,971 is 1
Step 1: Since 964 > 920, we apply the division lemma to 964 and 920, to get
964 = 920 x 1 + 44
Step 2: Since the reminder 920 ≠ 0, we apply division lemma to 44 and 920, to get
920 = 44 x 20 + 40
Step 3: We consider the new divisor 44 and the new remainder 40, and apply the division lemma to get
44 = 40 x 1 + 4
We consider the new divisor 40 and the new remainder 4, and apply the division lemma to get
40 = 4 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 964 and 920 is 4
Notice that 4 = HCF(40,4) = HCF(44,40) = HCF(920,44) = HCF(964,920) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 971 > 4, we apply the division lemma to 971 and 4, to get
971 = 4 x 242 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 971 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(971,4) .
