HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 850, 561, 581 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 850, 561, 581 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 850, 561, 581 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 850, 561, 581 is 1.
HCF(850, 561, 581) = 1
HCF of 850, 561, 581 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 850, 561, 581 is 1.
Highest Common Factor of 850,561,581 is 1
Step 1: Since 850 > 561, we apply the division lemma to 850 and 561, to get
850 = 561 x 1 + 289
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 289 and 561, to get
561 = 289 x 1 + 272
Step 3: We consider the new divisor 289 and the new remainder 272, and apply the division lemma to get
289 = 272 x 1 + 17
We consider the new divisor 272 and the new remainder 17, and apply the division lemma to get
272 = 17 x 16 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 17, the HCF of 850 and 561 is 17
Notice that 17 = HCF(272,17) = HCF(289,272) = HCF(561,289) = HCF(850,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 581 > 17, we apply the division lemma to 581 and 17, to get
581 = 17 x 34 + 3
Step 2: Since the reminder 17 ≠ 0, we apply division lemma to 3 and 17, to get
17 = 3 x 5 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 17 and 581 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(17,3) = HCF(581,17) .
