HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 70, 797, 160 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 70, 797, 160 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 70, 797, 160 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 70, 797, 160 is 1.
HCF(70, 797, 160) = 1
HCF of 70, 797, 160 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 70, 797, 160 is 1.
Highest Common Factor of 70,797,160 is 1
Step 1: Since 797 > 70, we apply the division lemma to 797 and 70, to get
797 = 70 x 11 + 27
Step 2: Since the reminder 70 ≠ 0, we apply division lemma to 27 and 70, to get
70 = 27 x 2 + 16
Step 3: We consider the new divisor 27 and the new remainder 16, and apply the division lemma to get
27 = 16 x 1 + 11
We consider the new divisor 16 and the new remainder 11,and apply the division lemma to get
16 = 11 x 1 + 5
We consider the new divisor 11 and the new remainder 5,and apply the division lemma to get
11 = 5 x 2 + 1
We consider the new divisor 5 and the new remainder 1,and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 70 and 797 is 1
Notice that 1 = HCF(5,1) = HCF(11,5) = HCF(16,11) = HCF(27,16) = HCF(70,27) = HCF(797,70) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 160 > 1, we apply the division lemma to 160 and 1, to get
160 = 1 x 160 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 160 is 1
Notice that 1 = HCF(160,1) .
