HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 548, 905, 684 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 548, 905, 684 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 548, 905, 684 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 548, 905, 684 is 1.
HCF(548, 905, 684) = 1
HCF of 548, 905, 684 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 548, 905, 684 is 1.
Highest Common Factor of 548,905,684 is 1
Step 1: Since 905 > 548, we apply the division lemma to 905 and 548, to get
905 = 548 x 1 + 357
Step 2: Since the reminder 548 ≠ 0, we apply division lemma to 357 and 548, to get
548 = 357 x 1 + 191
Step 3: We consider the new divisor 357 and the new remainder 191, and apply the division lemma to get
357 = 191 x 1 + 166
We consider the new divisor 191 and the new remainder 166,and apply the division lemma to get
191 = 166 x 1 + 25
We consider the new divisor 166 and the new remainder 25,and apply the division lemma to get
166 = 25 x 6 + 16
We consider the new divisor 25 and the new remainder 16,and apply the division lemma to get
25 = 16 x 1 + 9
We consider the new divisor 16 and the new remainder 9,and apply the division lemma to get
16 = 9 x 1 + 7
We consider the new divisor 9 and the new remainder 7,and apply the division lemma to get
9 = 7 x 1 + 2
We consider the new divisor 7 and the new remainder 2,and apply the division lemma to get
7 = 2 x 3 + 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 548 and 905 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(9,7) = HCF(16,9) = HCF(25,16) = HCF(166,25) = HCF(191,166) = HCF(357,191) = HCF(548,357) = HCF(905,548) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 684 > 1, we apply the division lemma to 684 and 1, to get
684 = 1 x 684 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 684 is 1
Notice that 1 = HCF(684,1) .
