HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 401 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 542, 401 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 542, 401 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 542, 401 is 1.
HCF(542, 401) = 1
HCF of 542, 401 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 542, 401 is 1.
Highest Common Factor of 542,401 is 1
Step 1: Since 542 > 401, we apply the division lemma to 542 and 401, to get
542 = 401 x 1 + 141
Step 2: Since the reminder 401 ≠ 0, we apply division lemma to 141 and 401, to get
401 = 141 x 2 + 119
Step 3: We consider the new divisor 141 and the new remainder 119, and apply the division lemma to get
141 = 119 x 1 + 22
We consider the new divisor 119 and the new remainder 22,and apply the division lemma to get
119 = 22 x 5 + 9
We consider the new divisor 22 and the new remainder 9,and apply the division lemma to get
22 = 9 x 2 + 4
We consider the new divisor 9 and the new remainder 4,and apply the division lemma to get
9 = 4 x 2 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 542 and 401 is 1
Notice that 1 = HCF(4,1) = HCF(9,4) = HCF(22,9) = HCF(119,22) = HCF(141,119) = HCF(401,141) = HCF(542,401) .
