HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 665, 238, 884 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 665, 238, 884 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 665, 238, 884 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 665, 238, 884 is 1.
HCF(665, 238, 884) = 1
HCF of 665, 238, 884 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 665, 238, 884 is 1.
Highest Common Factor of 665,238,884 is 1
Step 1: Since 665 > 238, we apply the division lemma to 665 and 238, to get
665 = 238 x 2 + 189
Step 2: Since the reminder 238 ≠ 0, we apply division lemma to 189 and 238, to get
238 = 189 x 1 + 49
Step 3: We consider the new divisor 189 and the new remainder 49, and apply the division lemma to get
189 = 49 x 3 + 42
We consider the new divisor 49 and the new remainder 42,and apply the division lemma to get
49 = 42 x 1 + 7
We consider the new divisor 42 and the new remainder 7,and apply the division lemma to get
42 = 7 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 7, the HCF of 665 and 238 is 7
Notice that 7 = HCF(42,7) = HCF(49,42) = HCF(189,49) = HCF(238,189) = HCF(665,238) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 884 > 7, we apply the division lemma to 884 and 7, to get
884 = 7 x 126 + 2
Step 2: Since the reminder 7 ≠ 0, we apply division lemma to 2 and 7, to get
7 = 2 x 3 + 1
Step 3: 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 7 and 884 is 1
Notice that 1 = HCF(2,1) = HCF(7,2) = HCF(884,7) .
