HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 643, 971, 848 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 643, 971, 848 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 643, 971, 848 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 643, 971, 848 is 1.
HCF(643, 971, 848) = 1
HCF of 643, 971, 848 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 643, 971, 848 is 1.
Highest Common Factor of 643,971,848 is 1
Step 1: Since 971 > 643, we apply the division lemma to 971 and 643, to get
971 = 643 x 1 + 328
Step 2: Since the reminder 643 ≠ 0, we apply division lemma to 328 and 643, to get
643 = 328 x 1 + 315
Step 3: We consider the new divisor 328 and the new remainder 315, and apply the division lemma to get
328 = 315 x 1 + 13
We consider the new divisor 315 and the new remainder 13,and apply the division lemma to get
315 = 13 x 24 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
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 643 and 971 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(315,13) = HCF(328,315) = HCF(643,328) = HCF(971,643) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 848 > 1, we apply the division lemma to 848 and 1, to get
848 = 1 x 848 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 848 is 1
Notice that 1 = HCF(848,1) .
