HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 767, 158 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 767, 158 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 767, 158 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 767, 158 is 1.
HCF(767, 158) = 1
HCF of 767, 158 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 767, 158 is 1.
Highest Common Factor of 767,158 is 1
Step 1: Since 767 > 158, we apply the division lemma to 767 and 158, to get
767 = 158 x 4 + 135
Step 2: Since the reminder 158 ≠ 0, we apply division lemma to 135 and 158, to get
158 = 135 x 1 + 23
Step 3: We consider the new divisor 135 and the new remainder 23, and apply the division lemma to get
135 = 23 x 5 + 20
We consider the new divisor 23 and the new remainder 20,and apply the division lemma to get
23 = 20 x 1 + 3
We consider the new divisor 20 and the new remainder 3,and apply the division lemma to get
20 = 3 x 6 + 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 767 and 158 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(20,3) = HCF(23,20) = HCF(135,23) = HCF(158,135) = HCF(767,158) .
