HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 979, 557, 859 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 979, 557, 859 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 979, 557, 859 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 979, 557, 859 is 1.
HCF(979, 557, 859) = 1
HCF of 979, 557, 859 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 979, 557, 859 is 1.
Highest Common Factor of 979,557,859 is 1
Step 1: Since 979 > 557, we apply the division lemma to 979 and 557, to get
979 = 557 x 1 + 422
Step 2: Since the reminder 557 ≠ 0, we apply division lemma to 422 and 557, to get
557 = 422 x 1 + 135
Step 3: We consider the new divisor 422 and the new remainder 135, and apply the division lemma to get
422 = 135 x 3 + 17
We consider the new divisor 135 and the new remainder 17,and apply the division lemma to get
135 = 17 x 7 + 16
We consider the new divisor 17 and the new remainder 16,and apply the division lemma to get
17 = 16 x 1 + 1
We consider the new divisor 16 and the new remainder 1,and apply the division lemma to get
16 = 1 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 979 and 557 is 1
Notice that 1 = HCF(16,1) = HCF(17,16) = HCF(135,17) = HCF(422,135) = HCF(557,422) = HCF(979,557) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 859 > 1, we apply the division lemma to 859 and 1, to get
859 = 1 x 859 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 859 is 1
Notice that 1 = HCF(859,1) .
