HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 480, 666 i.e. 6 the largest integer that leaves a remainder zero for all numbers.
HCF of 480, 666 is 6 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 480, 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 480, 666 is 6.
HCF(480, 666) = 6
HCF of 480, 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 480, 666 is 6.
Highest Common Factor of 480,666 is 6
Step 1: Since 666 > 480, we apply the division lemma to 666 and 480, to get
666 = 480 x 1 + 186
Step 2: Since the reminder 480 ≠ 0, we apply division lemma to 186 and 480, to get
480 = 186 x 2 + 108
Step 3: We consider the new divisor 186 and the new remainder 108, and apply the division lemma to get
186 = 108 x 1 + 78
We consider the new divisor 108 and the new remainder 78,and apply the division lemma to get
108 = 78 x 1 + 30
We consider the new divisor 78 and the new remainder 30,and apply the division lemma to get
78 = 30 x 2 + 18
We consider the new divisor 30 and the new remainder 18,and apply the division lemma to get
30 = 18 x 1 + 12
We consider the new divisor 18 and the new remainder 12,and apply the division lemma to get
18 = 12 x 1 + 6
We consider the new divisor 12 and the new remainder 6,and apply the division lemma to get
12 = 6 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 480 and 666 is 6
Notice that 6 = HCF(12,6) = HCF(18,12) = HCF(30,18) = HCF(78,30) = HCF(108,78) = HCF(186,108) = HCF(480,186) = HCF(666,480) .
