HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 170, 357, 205, 919 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 170, 357, 205, 919 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 170, 357, 205, 919 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 170, 357, 205, 919 is 1.
HCF(170, 357, 205, 919) = 1
HCF of 170, 357, 205, 919 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 170, 357, 205, 919 is 1.
Highest Common Factor of 170,357,205,919 is 1
Step 1: Since 357 > 170, we apply the division lemma to 357 and 170, to get
357 = 170 x 2 + 17
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 17 and 170, to get
170 = 17 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 170 and 357 is 17
Notice that 17 = HCF(170,17) = HCF(357,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 205 > 17, we apply the division lemma to 205 and 17, to get
205 = 17 x 12 + 1
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 1 and 17, to get
17 = 1 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 205 is 1
Notice that 1 = HCF(17,1) = HCF(205,17) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 919 > 1, we apply the division lemma to 919 and 1, to get
919 = 1 x 919 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 919 is 1
Notice that 1 = HCF(919,1) .
