HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 210, 310 i.e. 5 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 210, 310 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 665, 210, 310 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 665, 210, 310 is 5.
HCF(665, 210, 310) = 5
HCF of 665, 210, 310 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 210, 310 is 5.
Highest Common Factor of 665,210,310 is 5
Step 1: Since 665 > 210, we apply the division lemma to 665 and 210, to get
665 = 210 x 3 + 35
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 35 and 210, to get
210 = 35 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 35, the HCF of 665 and 210 is 35
Notice that 35 = HCF(210,35) = HCF(665,210) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 310 > 35, we apply the division lemma to 310 and 35, to get
310 = 35 x 8 + 30
Step 2: Since the reminder 35 ≠ 0, we apply division lemma to 30 and 35, to get
35 = 30 x 1 + 5
Step 3: 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 35 and 310 is 5
Notice that 5 = HCF(30,5) = HCF(35,30) = HCF(310,35) .
