HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 837, 406 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 837, 406 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 561, 837, 406 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 561, 837, 406 is 1.
HCF(561, 837, 406) = 1
HCF of 561, 837, 406 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 561, 837, 406 is 1.
Highest Common Factor of 561,837,406 is 1
Step 1: Since 837 > 561, we apply the division lemma to 837 and 561, to get
837 = 561 x 1 + 276
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 276 and 561, to get
561 = 276 x 2 + 9
Step 3: We consider the new divisor 276 and the new remainder 9, and apply the division lemma to get
276 = 9 x 30 + 6
We consider the new divisor 9 and the new remainder 6,and apply the division lemma to get
9 = 6 x 1 + 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 561 and 837 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(276,9) = HCF(561,276) = HCF(837,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 406 > 3, we apply the division lemma to 406 and 3, to get
406 = 3 x 135 + 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 406 is 1
Notice that 1 = HCF(3,1) = HCF(406,3) .
