HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 869, 613, 939 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 869, 613, 939 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 869, 613, 939 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 869, 613, 939 is 1.
HCF(869, 613, 939) = 1
HCF of 869, 613, 939 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 869, 613, 939 is 1.
Highest Common Factor of 869,613,939 is 1
Step 1: Since 869 > 613, we apply the division lemma to 869 and 613, to get
869 = 613 x 1 + 256
Step 2: Since the reminder 613 ≠ 0, we apply division lemma to 256 and 613, to get
613 = 256 x 2 + 101
Step 3: We consider the new divisor 256 and the new remainder 101, and apply the division lemma to get
256 = 101 x 2 + 54
We consider the new divisor 101 and the new remainder 54,and apply the division lemma to get
101 = 54 x 1 + 47
We consider the new divisor 54 and the new remainder 47,and apply the division lemma to get
54 = 47 x 1 + 7
We consider the new divisor 47 and the new remainder 7,and apply the division lemma to get
47 = 7 x 6 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 869 and 613 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(47,7) = HCF(54,47) = HCF(101,54) = HCF(256,101) = HCF(613,256) = HCF(869,613) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 939 > 1, we apply the division lemma to 939 and 1, to get
939 = 1 x 939 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 939 is 1
Notice that 1 = HCF(939,1) .
