HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 475, 666 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 475, 666 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 475, 666 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 475, 666 is 1.
HCF(475, 666) = 1
HCF of 475, 666 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 475, 666 is 1.
Highest Common Factor of 475,666 is 1
Step 1: Since 666 > 475, we apply the division lemma to 666 and 475, to get
666 = 475 x 1 + 191
Step 2: Since the reminder 475 ≠ 0, we apply division lemma to 191 and 475, to get
475 = 191 x 2 + 93
Step 3: We consider the new divisor 191 and the new remainder 93, and apply the division lemma to get
191 = 93 x 2 + 5
We consider the new divisor 93 and the new remainder 5,and apply the division lemma to get
93 = 5 x 18 + 3
We consider the new divisor 5 and the new remainder 3,and apply the division lemma to get
5 = 3 x 1 + 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 475 and 666 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(93,5) = HCF(191,93) = HCF(475,191) = HCF(666,475) .
