HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 541, 402 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 541, 402 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 541, 402 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 541, 402 is 1.
HCF(541, 402) = 1
HCF of 541, 402 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 541, 402 is 1.
Highest Common Factor of 541,402 is 1
Step 1: Since 541 > 402, we apply the division lemma to 541 and 402, to get
541 = 402 x 1 + 139
Step 2: Since the reminder 402 ≠ 0, we apply division lemma to 139 and 402, to get
402 = 139 x 2 + 124
Step 3: We consider the new divisor 139 and the new remainder 124, and apply the division lemma to get
139 = 124 x 1 + 15
We consider the new divisor 124 and the new remainder 15,and apply the division lemma to get
124 = 15 x 8 + 4
We consider the new divisor 15 and the new remainder 4,and apply the division lemma to get
15 = 4 x 3 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 541 and 402 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(15,4) = HCF(124,15) = HCF(139,124) = HCF(402,139) = HCF(541,402) .
