HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 551, 646, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 551, 646, 543 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 551, 646, 543 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 551, 646, 543 is 1.
HCF(551, 646, 543) = 1
HCF of 551, 646, 543 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 551, 646, 543 is 1.
Highest Common Factor of 551,646,543 is 1
Step 1: Since 646 > 551, we apply the division lemma to 646 and 551, to get
646 = 551 x 1 + 95
Step 2: Since the reminder 551 ≠ 0, we apply division lemma to 95 and 551, to get
551 = 95 x 5 + 76
Step 3: We consider the new divisor 95 and the new remainder 76, and apply the division lemma to get
95 = 76 x 1 + 19
We consider the new divisor 76 and the new remainder 19, and apply the division lemma to get
76 = 19 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 19, the HCF of 551 and 646 is 19
Notice that 19 = HCF(76,19) = HCF(95,76) = HCF(551,95) = HCF(646,551) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 543 > 19, we apply the division lemma to 543 and 19, to get
543 = 19 x 28 + 11
Step 2: Since the reminder 19 ≠ 0, we apply division lemma to 11 and 19, to get
19 = 11 x 1 + 8
Step 3: 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 19 and 543 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(8,3) = HCF(11,8) = HCF(19,11) = HCF(543,19) .
