HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 844, 971, 375, 391 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 844, 971, 375, 391 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 844, 971, 375, 391 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 844, 971, 375, 391 is 1.
HCF(844, 971, 375, 391) = 1
HCF of 844, 971, 375, 391 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 844, 971, 375, 391 is 1.
Highest Common Factor of 844,971,375,391 is 1
Step 1: Since 971 > 844, we apply the division lemma to 971 and 844, to get
971 = 844 x 1 + 127
Step 2: Since the reminder 844 ≠ 0, we apply division lemma to 127 and 844, to get
844 = 127 x 6 + 82
Step 3: We consider the new divisor 127 and the new remainder 82, and apply the division lemma to get
127 = 82 x 1 + 45
We consider the new divisor 82 and the new remainder 45,and apply the division lemma to get
82 = 45 x 1 + 37
We consider the new divisor 45 and the new remainder 37,and apply the division lemma to get
45 = 37 x 1 + 8
We consider the new divisor 37 and the new remainder 8,and apply the division lemma to get
37 = 8 x 4 + 5
We consider the new divisor 8 and the new remainder 5,and apply the division lemma to get
8 = 5 x 1 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1,and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 844 and 971 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(8,5) = HCF(37,8) = HCF(45,37) = HCF(82,45) = HCF(127,82) = HCF(844,127) = HCF(971,844) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 375 > 1, we apply the division lemma to 375 and 1, to get
375 = 1 x 375 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 375 is 1
Notice that 1 = HCF(375,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 391 > 1, we apply the division lemma to 391 and 1, to get
391 = 1 x 391 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 391 is 1
Notice that 1 = HCF(391,1) .
