HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 995, 688, 579 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 995, 688, 579 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 995, 688, 579 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 995, 688, 579 is 1.
HCF(995, 688, 579) = 1
HCF of 995, 688, 579 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 995, 688, 579 is 1.
Highest Common Factor of 995,688,579 is 1
Step 1: Since 995 > 688, we apply the division lemma to 995 and 688, to get
995 = 688 x 1 + 307
Step 2: Since the reminder 688 ≠ 0, we apply division lemma to 307 and 688, to get
688 = 307 x 2 + 74
Step 3: We consider the new divisor 307 and the new remainder 74, and apply the division lemma to get
307 = 74 x 4 + 11
We consider the new divisor 74 and the new remainder 11,and apply the division lemma to get
74 = 11 x 6 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 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 995 and 688 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(74,11) = HCF(307,74) = HCF(688,307) = HCF(995,688) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 579 > 1, we apply the division lemma to 579 and 1, to get
579 = 1 x 579 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 579 is 1
Notice that 1 = HCF(579,1) .
