HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 307, 785 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 307, 785 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 307, 785 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 307, 785 is 1.
HCF(307, 785) = 1
HCF of 307, 785 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 307, 785 is 1.
Highest Common Factor of 307,785 is 1
Step 1: Since 785 > 307, we apply the division lemma to 785 and 307, to get
785 = 307 x 2 + 171
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 171 and 307, to get
307 = 171 x 1 + 136
Step 3: We consider the new divisor 171 and the new remainder 136, and apply the division lemma to get
171 = 136 x 1 + 35
We consider the new divisor 136 and the new remainder 35,and apply the division lemma to get
136 = 35 x 3 + 31
We consider the new divisor 35 and the new remainder 31,and apply the division lemma to get
35 = 31 x 1 + 4
We consider the new divisor 31 and the new remainder 4,and apply the division lemma to get
31 = 4 x 7 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 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 307 and 785 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(31,4) = HCF(35,31) = HCF(136,35) = HCF(171,136) = HCF(307,171) = HCF(785,307) .
