HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 685, 114 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 685, 114 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 438, 685, 114 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 438, 685, 114 is 1.
HCF(438, 685, 114) = 1
HCF of 438, 685, 114 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 438, 685, 114 is 1.
Highest Common Factor of 438,685,114 is 1
Step 1: Since 685 > 438, we apply the division lemma to 685 and 438, to get
685 = 438 x 1 + 247
Step 2: Since the reminder 438 ≠ 0, we apply division lemma to 247 and 438, to get
438 = 247 x 1 + 191
Step 3: We consider the new divisor 247 and the new remainder 191, and apply the division lemma to get
247 = 191 x 1 + 56
We consider the new divisor 191 and the new remainder 56,and apply the division lemma to get
191 = 56 x 3 + 23
We consider the new divisor 56 and the new remainder 23,and apply the division lemma to get
56 = 23 x 2 + 10
We consider the new divisor 23 and the new remainder 10,and apply the division lemma to get
23 = 10 x 2 + 3
We consider the new divisor 10 and the new remainder 3,and apply the division lemma to get
10 = 3 x 3 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 438 and 685 is 1
Notice that 1 = HCF(3,1) = HCF(10,3) = HCF(23,10) = HCF(56,23) = HCF(191,56) = HCF(247,191) = HCF(438,247) = HCF(685,438) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 114 > 1, we apply the division lemma to 114 and 1, to get
114 = 1 x 114 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 114 is 1
Notice that 1 = HCF(114,1) .
