HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 239, 378, 207 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 239, 378, 207 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 239, 378, 207 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 239, 378, 207 is 1.
HCF(239, 378, 207) = 1
HCF of 239, 378, 207 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 239, 378, 207 is 1.
Highest Common Factor of 239,378,207 is 1
Step 1: Since 378 > 239, we apply the division lemma to 378 and 239, to get
378 = 239 x 1 + 139
Step 2: Since the reminder 239 ≠ 0, we apply division lemma to 139 and 239, to get
239 = 139 x 1 + 100
Step 3: We consider the new divisor 139 and the new remainder 100, and apply the division lemma to get
139 = 100 x 1 + 39
We consider the new divisor 100 and the new remainder 39,and apply the division lemma to get
100 = 39 x 2 + 22
We consider the new divisor 39 and the new remainder 22,and apply the division lemma to get
39 = 22 x 1 + 17
We consider the new divisor 22 and the new remainder 17,and apply the division lemma to get
22 = 17 x 1 + 5
We consider the new divisor 17 and the new remainder 5,and apply the division lemma to get
17 = 5 x 3 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 239 and 378 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(17,5) = HCF(22,17) = HCF(39,22) = HCF(100,39) = HCF(139,100) = HCF(239,139) = HCF(378,239) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 207 > 1, we apply the division lemma to 207 and 1, to get
207 = 1 x 207 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 207 is 1
Notice that 1 = HCF(207,1) .
