HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 310, 785 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 310, 785 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 310, 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 310, 785 is 5.
HCF(310, 785) = 5
HCF of 310, 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 310, 785 is 5.
Highest Common Factor of 310,785 is 5
Step 1: Since 785 > 310, we apply the division lemma to 785 and 310, to get
785 = 310 x 2 + 165
Step 2: Since the reminder 310 ≠ 0, we apply division lemma to 165 and 310, to get
310 = 165 x 1 + 145
Step 3: We consider the new divisor 165 and the new remainder 145, and apply the division lemma to get
165 = 145 x 1 + 20
We consider the new divisor 145 and the new remainder 20,and apply the division lemma to get
145 = 20 x 7 + 5
We consider the new divisor 20 and the new remainder 5,and apply the division lemma to get
20 = 5 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 310 and 785 is 5
Notice that 5 = HCF(20,5) = HCF(145,20) = HCF(165,145) = HCF(310,165) = HCF(785,310) .
