HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 822, 853 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 822, 853 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 615, 822, 853 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 615, 822, 853 is 1.
HCF(615, 822, 853) = 1
HCF of 615, 822, 853 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 615, 822, 853 is 1.
Highest Common Factor of 615,822,853 is 1
Step 1: Since 822 > 615, we apply the division lemma to 822 and 615, to get
822 = 615 x 1 + 207
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 207 and 615, to get
615 = 207 x 2 + 201
Step 3: We consider the new divisor 207 and the new remainder 201, and apply the division lemma to get
207 = 201 x 1 + 6
We consider the new divisor 201 and the new remainder 6,and apply the division lemma to get
201 = 6 x 33 + 3
We consider the new divisor 6 and the new remainder 3,and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 615 and 822 is 3
Notice that 3 = HCF(6,3) = HCF(201,6) = HCF(207,201) = HCF(615,207) = HCF(822,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 853 > 3, we apply the division lemma to 853 and 3, to get
853 = 3 x 284 + 1
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 1 and 3, to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 853 is 1
Notice that 1 = HCF(3,1) = HCF(853,3) .
