HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 210, 802 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 210, 802 is 2 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 210, 802 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 210, 802 is 2.
HCF(210, 802) = 2
HCF of 210, 802 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 210, 802 is 2.
Highest Common Factor of 210,802 is 2
Step 1: Since 802 > 210, we apply the division lemma to 802 and 210, to get
802 = 210 x 3 + 172
Step 2: Since the reminder 210 ≠ 0, we apply division lemma to 172 and 210, to get
210 = 172 x 1 + 38
Step 3: We consider the new divisor 172 and the new remainder 38, and apply the division lemma to get
172 = 38 x 4 + 20
We consider the new divisor 38 and the new remainder 20,and apply the division lemma to get
38 = 20 x 1 + 18
We consider the new divisor 20 and the new remainder 18,and apply the division lemma to get
20 = 18 x 1 + 2
We consider the new divisor 18 and the new remainder 2,and apply the division lemma to get
18 = 2 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 210 and 802 is 2
Notice that 2 = HCF(18,2) = HCF(20,18) = HCF(38,20) = HCF(172,38) = HCF(210,172) = HCF(802,210) .
