HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 355, 543 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 355, 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 355, 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 355, 543 is 1.
HCF(355, 543) = 1
HCF of 355, 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 355, 543 is 1.
Highest Common Factor of 355,543 is 1
Step 1: Since 543 > 355, we apply the division lemma to 543 and 355, to get
543 = 355 x 1 + 188
Step 2: Since the reminder 355 ≠ 0, we apply division lemma to 188 and 355, to get
355 = 188 x 1 + 167
Step 3: We consider the new divisor 188 and the new remainder 167, and apply the division lemma to get
188 = 167 x 1 + 21
We consider the new divisor 167 and the new remainder 21,and apply the division lemma to get
167 = 21 x 7 + 20
We consider the new divisor 21 and the new remainder 20,and apply the division lemma to get
21 = 20 x 1 + 1
We consider the new divisor 20 and the new remainder 1,and apply the division lemma to get
20 = 1 x 20 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 355 and 543 is 1
Notice that 1 = HCF(20,1) = HCF(21,20) = HCF(167,21) = HCF(188,167) = HCF(355,188) = HCF(543,355) .
