HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 843, 736 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 843, 736 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, 843, 736 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, 843, 736 is 1.
HCF(561, 843, 736) = 1
HCF of 561, 843, 736 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, 843, 736 is 1.
Highest Common Factor of 561,843,736 is 1
Step 1: Since 843 > 561, we apply the division lemma to 843 and 561, to get
843 = 561 x 1 + 282
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 282 and 561, to get
561 = 282 x 1 + 279
Step 3: We consider the new divisor 282 and the new remainder 279, and apply the division lemma to get
282 = 279 x 1 + 3
We consider the new divisor 279 and the new remainder 3, and apply the division lemma to get
279 = 3 x 93 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 561 and 843 is 3
Notice that 3 = HCF(279,3) = HCF(282,279) = HCF(561,282) = HCF(843,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 736 > 3, we apply the division lemma to 736 and 3, to get
736 = 3 x 245 + 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 736 is 1
Notice that 1 = HCF(3,1) = HCF(736,3) .
