HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 714, 189, 814 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 714, 189, 814 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 714, 189, 814 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 714, 189, 814 is 1.
HCF(714, 189, 814) = 1
HCF of 714, 189, 814 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 714, 189, 814 is 1.
Highest Common Factor of 714,189,814 is 1
Step 1: Since 714 > 189, we apply the division lemma to 714 and 189, to get
714 = 189 x 3 + 147
Step 2: Since the reminder 189 ≠ 0, we apply division lemma to 147 and 189, to get
189 = 147 x 1 + 42
Step 3: We consider the new divisor 147 and the new remainder 42, and apply the division lemma to get
147 = 42 x 3 + 21
We consider the new divisor 42 and the new remainder 21, and apply the division lemma to get
42 = 21 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 714 and 189 is 21
Notice that 21 = HCF(42,21) = HCF(147,42) = HCF(189,147) = HCF(714,189) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 814 > 21, we apply the division lemma to 814 and 21, to get
814 = 21 x 38 + 16
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 16 and 21, to get
21 = 16 x 1 + 5
Step 3: We consider the new divisor 16 and the new remainder 5, and apply the division lemma to get
16 = 5 x 3 + 1
We consider the new divisor 5 and the new remainder 1, and apply the division lemma to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 21 and 814 is 1
Notice that 1 = HCF(5,1) = HCF(16,5) = HCF(21,16) = HCF(814,21) .
