HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 628, 551, 682 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 628, 551, 682 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 628, 551, 682 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 628, 551, 682 is 1.
HCF(628, 551, 682) = 1
HCF of 628, 551, 682 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 628, 551, 682 is 1.
Highest Common Factor of 628,551,682 is 1
Step 1: Since 628 > 551, we apply the division lemma to 628 and 551, to get
628 = 551 x 1 + 77
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 77 and 551, to get
551 = 77 x 7 + 12
Step 3: We consider the new divisor 77 and the new remainder 12, and apply the division lemma to get
77 = 12 x 6 + 5
We consider the new divisor 12 and the new remainder 5,and apply the division lemma to get
12 = 5 x 2 + 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 628 and 551 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(12,5) = HCF(77,12) = HCF(551,77) = HCF(628,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 682 > 1, we apply the division lemma to 682 and 1, to get
682 = 1 x 682 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 682 is 1
Notice that 1 = HCF(682,1) .
