HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 256, 915, 61 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 256, 915, 61 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 256, 915, 61 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 256, 915, 61 is 1.
HCF(256, 915, 61) = 1
HCF of 256, 915, 61 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 256, 915, 61 is 1.
Highest Common Factor of 256,915,61 is 1
Step 1: Since 915 > 256, we apply the division lemma to 915 and 256, to get
915 = 256 x 3 + 147
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 147 and 256, to get
256 = 147 x 1 + 109
Step 3: We consider the new divisor 147 and the new remainder 109, and apply the division lemma to get
147 = 109 x 1 + 38
We consider the new divisor 109 and the new remainder 38,and apply the division lemma to get
109 = 38 x 2 + 33
We consider the new divisor 38 and the new remainder 33,and apply the division lemma to get
38 = 33 x 1 + 5
We consider the new divisor 33 and the new remainder 5,and apply the division lemma to get
33 = 5 x 6 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 2
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 256 and 915 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(33,5) = HCF(38,33) = HCF(109,38) = HCF(147,109) = HCF(256,147) = HCF(915,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 61 > 1, we apply the division lemma to 61 and 1, to get
61 = 1 x 61 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 61 is 1
Notice that 1 = HCF(61,1) .
