HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 770, 4139 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 770, 4139 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 770, 4139 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 770, 4139 is 1.
HCF(770, 4139) = 1
HCF of 770, 4139 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 770, 4139 is 1.
Highest Common Factor of 770,4139 is 1
Step 1: Since 4139 > 770, we apply the division lemma to 4139 and 770, to get
4139 = 770 x 5 + 289
Step 2: Since the reminder 770 ≠ 0, we apply division lemma to 289 and 770, to get
770 = 289 x 2 + 192
Step 3: We consider the new divisor 289 and the new remainder 192, and apply the division lemma to get
289 = 192 x 1 + 97
We consider the new divisor 192 and the new remainder 97,and apply the division lemma to get
192 = 97 x 1 + 95
We consider the new divisor 97 and the new remainder 95,and apply the division lemma to get
97 = 95 x 1 + 2
We consider the new divisor 95 and the new remainder 2,and apply the division lemma to get
95 = 2 x 47 + 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 770 and 4139 is 1
Notice that 1 = HCF(2,1) = HCF(95,2) = HCF(97,95) = HCF(192,97) = HCF(289,192) = HCF(770,289) = HCF(4139,770) .
