HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 867, 670, 181 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 867, 670, 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 867, 670, 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 867, 670, 181 is 1.
HCF(867, 670, 181) = 1
HCF of 867, 670, 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 867, 670, 181 is 1.
Highest Common Factor of 867,670,181 is 1
Step 1: Since 867 > 670, we apply the division lemma to 867 and 670, to get
867 = 670 x 1 + 197
Step 2: Since the reminder 670 ≠ 0, we apply division lemma to 197 and 670, to get
670 = 197 x 3 + 79
Step 3: We consider the new divisor 197 and the new remainder 79, and apply the division lemma to get
197 = 79 x 2 + 39
We consider the new divisor 79 and the new remainder 39,and apply the division lemma to get
79 = 39 x 2 + 1
We consider the new divisor 39 and the new remainder 1,and apply the division lemma to get
39 = 1 x 39 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 867 and 670 is 1
Notice that 1 = HCF(39,1) = HCF(79,39) = HCF(197,79) = HCF(670,197) = HCF(867,670) .
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) .
