HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 209, 792, 802 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 209, 792, 802 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 209, 792, 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 209, 792, 802 is 1.
HCF(209, 792, 802) = 1
HCF of 209, 792, 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 209, 792, 802 is 1.
Highest Common Factor of 209,792,802 is 1
Step 1: Since 792 > 209, we apply the division lemma to 792 and 209, to get
792 = 209 x 3 + 165
Step 2: Since the reminder 209 ≠ 0, we apply division lemma to 165 and 209, to get
209 = 165 x 1 + 44
Step 3: We consider the new divisor 165 and the new remainder 44, and apply the division lemma to get
165 = 44 x 3 + 33
We consider the new divisor 44 and the new remainder 33,and apply the division lemma to get
44 = 33 x 1 + 11
We consider the new divisor 33 and the new remainder 11,and apply the division lemma to get
33 = 11 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 11, the HCF of 209 and 792 is 11
Notice that 11 = HCF(33,11) = HCF(44,33) = HCF(165,44) = HCF(209,165) = HCF(792,209) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 802 > 11, we apply the division lemma to 802 and 11, to get
802 = 11 x 72 + 10
Step 2: Since the reminder 11 ≠ 0, we apply division lemma to 10 and 11, to get
11 = 10 x 1 + 1
Step 3: We consider the new divisor 10 and the new remainder 1, and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 11 and 802 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(802,11) .
