HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 84, 705 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 84, 705 is 3 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 84, 705 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 84, 705 is 3.
HCF(84, 705) = 3
HCF of 84, 705 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 84, 705 is 3.
Highest Common Factor of 84,705 is 3
Step 1: Since 705 > 84, we apply the division lemma to 705 and 84, to get
705 = 84 x 8 + 33
Step 2: Since the reminder 84 ≠ 0, we apply division lemma to 33 and 84, to get
84 = 33 x 2 + 18
Step 3: We consider the new divisor 33 and the new remainder 18, and apply the division lemma to get
33 = 18 x 1 + 15
We consider the new divisor 18 and the new remainder 15,and apply the division lemma to get
18 = 15 x 1 + 3
We consider the new divisor 15 and the new remainder 3,and apply the division lemma to get
15 = 3 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 84 and 705 is 3
Notice that 3 = HCF(15,3) = HCF(18,15) = HCF(33,18) = HCF(84,33) = HCF(705,84) .
