HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 685, 334, 551 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 685, 334, 551 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 685, 334, 551 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 685, 334, 551 is 1.
HCF(685, 334, 551) = 1
HCF of 685, 334, 551 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 685, 334, 551 is 1.
Highest Common Factor of 685,334,551 is 1
Step 1: Since 685 > 334, we apply the division lemma to 685 and 334, to get
685 = 334 x 2 + 17
Step 2: Since the reminder 334 ≠ 0, we apply division lemma to 17 and 334, to get
334 = 17 x 19 + 11
Step 3: We consider the new divisor 17 and the new remainder 11, and apply the division lemma to get
17 = 11 x 1 + 6
We consider the new divisor 11 and the new remainder 6,and apply the division lemma to get
11 = 6 x 1 + 5
We consider the new divisor 6 and the new remainder 5,and apply the division lemma to get
6 = 5 x 1 + 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 685 and 334 is 1
Notice that 1 = HCF(5,1) = HCF(6,5) = HCF(11,6) = HCF(17,11) = HCF(334,17) = HCF(685,334) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 551 > 1, we apply the division lemma to 551 and 1, to get
551 = 1 x 551 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 551 is 1
Notice that 1 = HCF(551,1) .
