HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 382, 660 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 382, 660 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 382, 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 382, 660 is 2.
HCF(382, 660) = 2
HCF of 382, 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 382, 660 is 2.
Highest Common Factor of 382,660 is 2
Step 1: Since 660 > 382, we apply the division lemma to 660 and 382, to get
660 = 382 x 1 + 278
Step 2: Since the reminder 382 ≠ 0, we apply division lemma to 278 and 382, to get
382 = 278 x 1 + 104
Step 3: We consider the new divisor 278 and the new remainder 104, and apply the division lemma to get
278 = 104 x 2 + 70
We consider the new divisor 104 and the new remainder 70,and apply the division lemma to get
104 = 70 x 1 + 34
We consider the new divisor 70 and the new remainder 34,and apply the division lemma to get
70 = 34 x 2 + 2
We consider the new divisor 34 and the new remainder 2,and apply the division lemma to get
34 = 2 x 17 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 382 and 660 is 2
Notice that 2 = HCF(34,2) = HCF(70,34) = HCF(104,70) = HCF(278,104) = HCF(382,278) = HCF(660,382) .
