HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 308, 714, 666 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 308, 714, 666 is 2 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 308, 714, 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 308, 714, 666 is 2.
HCF(308, 714, 666) = 2
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 308, 714, 666 is 2.
Step 1: Since 714 > 308, we apply the division lemma to 714 and 308, to get
714 = 308 x 2 + 98
Step 2: Since the reminder 308 ≠ 0, we apply division lemma to 98 and 308, to get
308 = 98 x 3 + 14
Step 3: We consider the new divisor 98 and the new remainder 14, and apply the division lemma to get
98 = 14 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 308 and 714 is 14
Notice that 14 = HCF(98,14) = HCF(308,98) = HCF(714,308) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 666 > 14, we apply the division lemma to 666 and 14, to get
666 = 14 x 47 + 8
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 8 and 14, to get
14 = 8 x 1 + 6
Step 3: We consider the new divisor 8 and the new remainder 6, and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 666 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(666,14) .
Here are some samples of HCF using Euclid's Algorithm calculations.
