HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 404, 655 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 404, 655 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 404, 655 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 404, 655 is 1.
HCF(404, 655) = 1
HCF of 404, 655 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 404, 655 is 1.
Highest Common Factor of 404,655 is 1
Step 1: Since 655 > 404, we apply the division lemma to 655 and 404, to get
655 = 404 x 1 + 251
Step 2: Since the reminder 404 ≠ 0, we apply division lemma to 251 and 404, to get
404 = 251 x 1 + 153
Step 3: We consider the new divisor 251 and the new remainder 153, and apply the division lemma to get
251 = 153 x 1 + 98
We consider the new divisor 153 and the new remainder 98,and apply the division lemma to get
153 = 98 x 1 + 55
We consider the new divisor 98 and the new remainder 55,and apply the division lemma to get
98 = 55 x 1 + 43
We consider the new divisor 55 and the new remainder 43,and apply the division lemma to get
55 = 43 x 1 + 12
We consider the new divisor 43 and the new remainder 12,and apply the division lemma to get
43 = 12 x 3 + 7
We consider the new divisor 12 and the new remainder 7,and apply the division lemma to get
12 = 7 x 1 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 404 and 655 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(12,7) = HCF(43,12) = HCF(55,43) = HCF(98,55) = HCF(153,98) = HCF(251,153) = HCF(404,251) = HCF(655,404) .
