HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 543, 698 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 543, 698 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 543, 698 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 543, 698 is 1.
HCF(543, 698) = 1
HCF of 543, 698 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 543, 698 is 1.
Highest Common Factor of 543,698 is 1
Step 1: Since 698 > 543, we apply the division lemma to 698 and 543, to get
698 = 543 x 1 + 155
Step 2: Since the reminder 543 ≠ 0, we apply division lemma to 155 and 543, to get
543 = 155 x 3 + 78
Step 3: We consider the new divisor 155 and the new remainder 78, and apply the division lemma to get
155 = 78 x 1 + 77
We consider the new divisor 78 and the new remainder 77,and apply the division lemma to get
78 = 77 x 1 + 1
We consider the new divisor 77 and the new remainder 1,and apply the division lemma to get
77 = 1 x 77 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 543 and 698 is 1
Notice that 1 = HCF(77,1) = HCF(78,77) = HCF(155,78) = HCF(543,155) = HCF(698,543) .
