HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 870, 995, 994 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 870, 995, 994 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 870, 995, 994 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 870, 995, 994 is 1.
HCF(870, 995, 994) = 1
HCF of 870, 995, 994 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 870, 995, 994 is 1.
Highest Common Factor of 870,995,994 is 1
Step 1: Since 995 > 870, we apply the division lemma to 995 and 870, to get
995 = 870 x 1 + 125
Step 2: Since the reminder 870 ≠ 0, we apply division lemma to 125 and 870, to get
870 = 125 x 6 + 120
Step 3: We consider the new divisor 125 and the new remainder 120, and apply the division lemma to get
125 = 120 x 1 + 5
We consider the new divisor 120 and the new remainder 5, and apply the division lemma to get
120 = 5 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 870 and 995 is 5
Notice that 5 = HCF(120,5) = HCF(125,120) = HCF(870,125) = HCF(995,870) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 994 > 5, we apply the division lemma to 994 and 5, to get
994 = 5 x 198 + 4
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 4 and 5, to get
5 = 4 x 1 + 1
Step 3: We consider the new divisor 4 and the new remainder 1, and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 994 is 1
Notice that 1 = HCF(4,1) = HCF(5,4) = HCF(994,5) .
