HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 561, 208, 936 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 561, 208, 936 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, 208, 936 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, 208, 936 is 1.
HCF(561, 208, 936) = 1
HCF of 561, 208, 936 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, 208, 936 is 1.
Highest Common Factor of 561,208,936 is 1
Step 1: Since 561 > 208, we apply the division lemma to 561 and 208, to get
561 = 208 x 2 + 145
Step 2: Since the reminder 208 ≠ 0, we apply division lemma to 145 and 208, to get
208 = 145 x 1 + 63
Step 3: We consider the new divisor 145 and the new remainder 63, and apply the division lemma to get
145 = 63 x 2 + 19
We consider the new divisor 63 and the new remainder 19,and apply the division lemma to get
63 = 19 x 3 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 561 and 208 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(63,19) = HCF(145,63) = HCF(208,145) = HCF(561,208) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 936 > 1, we apply the division lemma to 936 and 1, to get
936 = 1 x 936 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 936 is 1
Notice that 1 = HCF(936,1) .
