HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 887, 358 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 887, 358 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, 887, 358 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, 887, 358 is 1.
HCF(561, 887, 358) = 1
HCF of 561, 887, 358 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, 887, 358 is 1.
Highest Common Factor of 561,887,358 is 1
Step 1: Since 887 > 561, we apply the division lemma to 887 and 561, to get
887 = 561 x 1 + 326
Step 2: Since the reminder 561 ≠ 0, we apply division lemma to 326 and 561, to get
561 = 326 x 1 + 235
Step 3: We consider the new divisor 326 and the new remainder 235, and apply the division lemma to get
326 = 235 x 1 + 91
We consider the new divisor 235 and the new remainder 91,and apply the division lemma to get
235 = 91 x 2 + 53
We consider the new divisor 91 and the new remainder 53,and apply the division lemma to get
91 = 53 x 1 + 38
We consider the new divisor 53 and the new remainder 38,and apply the division lemma to get
53 = 38 x 1 + 15
We consider the new divisor 38 and the new remainder 15,and apply the division lemma to get
38 = 15 x 2 + 8
We consider the new divisor 15 and the new remainder 8,and apply the division lemma to get
15 = 8 x 1 + 7
We consider the new divisor 8 and the new remainder 7,and apply the division lemma to get
8 = 7 x 1 + 1
We consider the new divisor 7 and the new remainder 1,and apply the division lemma to get
7 = 1 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 561 and 887 is 1
Notice that 1 = HCF(7,1) = HCF(8,7) = HCF(15,8) = HCF(38,15) = HCF(53,38) = HCF(91,53) = HCF(235,91) = HCF(326,235) = HCF(561,326) = HCF(887,561) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 358 > 1, we apply the division lemma to 358 and 1, to get
358 = 1 x 358 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 358 is 1
Notice that 1 = HCF(358,1) .
