HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 714, 821, 662 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 714, 821, 662 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, 821, 662 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, 821, 662 is 1.
HCF(714, 821, 662) = 1
HCF of 714, 821, 662 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, 821, 662 is 1.
Highest Common Factor of 714,821,662 is 1
Step 1: Since 821 > 714, we apply the division lemma to 821 and 714, to get
821 = 714 x 1 + 107
Step 2: Since the reminder 714 ≠ 0, we apply division lemma to 107 and 714, to get
714 = 107 x 6 + 72
Step 3: We consider the new divisor 107 and the new remainder 72, and apply the division lemma to get
107 = 72 x 1 + 35
We consider the new divisor 72 and the new remainder 35,and apply the division lemma to get
72 = 35 x 2 + 2
We consider the new divisor 35 and the new remainder 2,and apply the division lemma to get
35 = 2 x 17 + 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 714 and 821 is 1
Notice that 1 = HCF(2,1) = HCF(35,2) = HCF(72,35) = HCF(107,72) = HCF(714,107) = HCF(821,714) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 662 > 1, we apply the division lemma to 662 and 1, to get
662 = 1 x 662 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 662 is 1
Notice that 1 = HCF(662,1) .
