HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 601, 256, 665 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 601, 256, 665 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 601, 256, 665 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 601, 256, 665 is 1.
HCF(601, 256, 665) = 1
HCF of 601, 256, 665 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 601, 256, 665 is 1.
Highest Common Factor of 601,256,665 is 1
Step 1: Since 601 > 256, we apply the division lemma to 601 and 256, to get
601 = 256 x 2 + 89
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 89 and 256, to get
256 = 89 x 2 + 78
Step 3: We consider the new divisor 89 and the new remainder 78, and apply the division lemma to get
89 = 78 x 1 + 11
We consider the new divisor 78 and the new remainder 11,and apply the division lemma to get
78 = 11 x 7 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 601 and 256 is 1
Notice that 1 = HCF(11,1) = HCF(78,11) = HCF(89,78) = HCF(256,89) = HCF(601,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 665 > 1, we apply the division lemma to 665 and 1, to get
665 = 1 x 665 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 665 is 1
Notice that 1 = HCF(665,1) .
