HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 554, 685, 706 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 554, 685, 706 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 554, 685, 706 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 554, 685, 706 is 1.
HCF(554, 685, 706) = 1
HCF of 554, 685, 706 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 554, 685, 706 is 1.
Highest Common Factor of 554,685,706 is 1
Step 1: Since 685 > 554, we apply the division lemma to 685 and 554, to get
685 = 554 x 1 + 131
Step 2: Since the reminder 554 ≠ 0, we apply division lemma to 131 and 554, to get
554 = 131 x 4 + 30
Step 3: We consider the new divisor 131 and the new remainder 30, and apply the division lemma to get
131 = 30 x 4 + 11
We consider the new divisor 30 and the new remainder 11,and apply the division lemma to get
30 = 11 x 2 + 8
We consider the new divisor 11 and the new remainder 8,and apply the division lemma to get
11 = 8 x 1 + 3
We consider the new divisor 8 and the new remainder 3,and apply the division lemma to get
8 = 3 x 2 + 2
We consider the new divisor 3 and the new remainder 2,and apply the division lemma to get
3 = 2 x 1 + 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 554 and 685 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(30,11) = HCF(131,30) = HCF(554,131) = HCF(685,554) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 706 > 1, we apply the division lemma to 706 and 1, to get
706 = 1 x 706 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 706 is 1
Notice that 1 = HCF(706,1) .
