HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 679, 256, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 679, 256, 181 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 679, 256, 181 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 679, 256, 181 is 1.
HCF(679, 256, 181) = 1
HCF of 679, 256, 181 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 679, 256, 181 is 1.
Highest Common Factor of 679,256,181 is 1
Step 1: Since 679 > 256, we apply the division lemma to 679 and 256, to get
679 = 256 x 2 + 167
Step 2: Since the reminder 256 ≠ 0, we apply division lemma to 167 and 256, to get
256 = 167 x 1 + 89
Step 3: We consider the new divisor 167 and the new remainder 89, and apply the division lemma to get
167 = 89 x 1 + 78
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 679 and 256 is 1
Notice that 1 = HCF(11,1) = HCF(78,11) = HCF(89,78) = HCF(167,89) = HCF(256,167) = HCF(679,256) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 181 > 1, we apply the division lemma to 181 and 1, to get
181 = 1 x 181 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 181 is 1
Notice that 1 = HCF(181,1) .
