HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 785, 859 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 785, 859 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 785, 859 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, 859 is 1.
HCF(785, 859) = 1
HCF of 785, 859 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, 859 is 1.
Highest Common Factor of 785,859 is 1
Step 1: Since 859 > 785, we apply the division lemma to 859 and 785, to get
859 = 785 x 1 + 74
Step 2: Since the reminder 785 ≠ 0, we apply division lemma to 74 and 785, to get
785 = 74 x 10 + 45
Step 3: We consider the new divisor 74 and the new remainder 45, and apply the division lemma to get
74 = 45 x 1 + 29
We consider the new divisor 45 and the new remainder 29,and apply the division lemma to get
45 = 29 x 1 + 16
We consider the new divisor 29 and the new remainder 16,and apply the division lemma to get
29 = 16 x 1 + 13
We consider the new divisor 16 and the new remainder 13,and apply the division lemma to get
16 = 13 x 1 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 785 and 859 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(16,13) = HCF(29,16) = HCF(45,29) = HCF(74,45) = HCF(785,74) = HCF(859,785) .
