HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 469, 660 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 469, 660 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 469, 660 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 469, 660 is 1.
HCF(469, 660) = 1
HCF of 469, 660 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 469, 660 is 1.
Highest Common Factor of 469,660 is 1
Step 1: Since 660 > 469, we apply the division lemma to 660 and 469, to get
660 = 469 x 1 + 191
Step 2: Since the reminder 469 ≠ 0, we apply division lemma to 191 and 469, to get
469 = 191 x 2 + 87
Step 3: We consider the new divisor 191 and the new remainder 87, and apply the division lemma to get
191 = 87 x 2 + 17
We consider the new divisor 87 and the new remainder 17,and apply the division lemma to get
87 = 17 x 5 + 2
We consider the new divisor 17 and the new remainder 2,and apply the division lemma to get
17 = 2 x 8 + 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 469 and 660 is 1
Notice that 1 = HCF(2,1) = HCF(17,2) = HCF(87,17) = HCF(191,87) = HCF(469,191) = HCF(660,469) .
