HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 917, 321, 559 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 917, 321, 559 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 917, 321, 559 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 917, 321, 559 is 1.
HCF(917, 321, 559) = 1
HCF of 917, 321, 559 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 917, 321, 559 is 1.
Highest Common Factor of 917,321,559 is 1
Step 1: Since 917 > 321, we apply the division lemma to 917 and 321, to get
917 = 321 x 2 + 275
Step 2: Since the reminder 321 ≠ 0, we apply division lemma to 275 and 321, to get
321 = 275 x 1 + 46
Step 3: We consider the new divisor 275 and the new remainder 46, and apply the division lemma to get
275 = 46 x 5 + 45
We consider the new divisor 46 and the new remainder 45,and apply the division lemma to get
46 = 45 x 1 + 1
We consider the new divisor 45 and the new remainder 1,and apply the division lemma to get
45 = 1 x 45 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 917 and 321 is 1
Notice that 1 = HCF(45,1) = HCF(46,45) = HCF(275,46) = HCF(321,275) = HCF(917,321) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 559 > 1, we apply the division lemma to 559 and 1, to get
559 = 1 x 559 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 559 is 1
Notice that 1 = HCF(559,1) .
