HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 615, 959, 809, 199 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 615, 959, 809, 199 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, 959, 809, 199 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, 959, 809, 199 is 1.
HCF(615, 959, 809, 199) = 1
HCF of 615, 959, 809, 199 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, 959, 809, 199 is 1.
Highest Common Factor of 615,959,809,199 is 1
Step 1: Since 959 > 615, we apply the division lemma to 959 and 615, to get
959 = 615 x 1 + 344
Step 2: Since the reminder 615 ≠ 0, we apply division lemma to 344 and 615, to get
615 = 344 x 1 + 271
Step 3: We consider the new divisor 344 and the new remainder 271, and apply the division lemma to get
344 = 271 x 1 + 73
We consider the new divisor 271 and the new remainder 73,and apply the division lemma to get
271 = 73 x 3 + 52
We consider the new divisor 73 and the new remainder 52,and apply the division lemma to get
73 = 52 x 1 + 21
We consider the new divisor 52 and the new remainder 21,and apply the division lemma to get
52 = 21 x 2 + 10
We consider the new divisor 21 and the new remainder 10,and apply the division lemma to get
21 = 10 x 2 + 1
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 615 and 959 is 1
Notice that 1 = HCF(10,1) = HCF(21,10) = HCF(52,21) = HCF(73,52) = HCF(271,73) = HCF(344,271) = HCF(615,344) = HCF(959,615) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 809 > 1, we apply the division lemma to 809 and 1, to get
809 = 1 x 809 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 809 is 1
Notice that 1 = HCF(809,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 199 > 1, we apply the division lemma to 199 and 1, to get
199 = 1 x 199 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 199 is 1
Notice that 1 = HCF(199,1) .
