HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 789, 307 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 789, 307 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 789, 307 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 789, 307 is 1.
HCF(789, 307) = 1
HCF of 789, 307 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 789, 307 is 1.
Highest Common Factor of 789,307 is 1
Step 1: Since 789 > 307, we apply the division lemma to 789 and 307, to get
789 = 307 x 2 + 175
Step 2: Since the reminder 307 ≠ 0, we apply division lemma to 175 and 307, to get
307 = 175 x 1 + 132
Step 3: We consider the new divisor 175 and the new remainder 132, and apply the division lemma to get
175 = 132 x 1 + 43
We consider the new divisor 132 and the new remainder 43,and apply the division lemma to get
132 = 43 x 3 + 3
We consider the new divisor 43 and the new remainder 3,and apply the division lemma to get
43 = 3 x 14 + 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 789 and 307 is 1
Notice that 1 = HCF(3,1) = HCF(43,3) = HCF(132,43) = HCF(175,132) = HCF(307,175) = HCF(789,307) .
