HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 4130 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 4130 is 5 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 785, 4130 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 785, 4130 is 5.
HCF(785, 4130) = 5
HCF of 785, 4130 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 785, 4130 is 5.
Highest Common Factor of 785,4130 is 5
Step 1: Since 4130 > 785, we apply the division lemma to 4130 and 785, to get
4130 = 785 x 5 + 205
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 205 and 785, to get
785 = 205 x 3 + 170
Step 3: We consider the new divisor 205 and the new remainder 170, and apply the division lemma to get
205 = 170 x 1 + 35
We consider the new divisor 170 and the new remainder 35,and apply the division lemma to get
170 = 35 x 4 + 30
We consider the new divisor 35 and the new remainder 30,and apply the division lemma to get
35 = 30 x 1 + 5
We consider the new divisor 30 and the new remainder 5,and apply the division lemma to get
30 = 5 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 785 and 4130 is 5
Notice that 5 = HCF(30,5) = HCF(35,30) = HCF(170,35) = HCF(205,170) = HCF(785,205) = HCF(4130,785) .
