HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 997, 380, 501 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 997, 380, 501 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 997, 380, 501 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 997, 380, 501 is 1.
HCF(997, 380, 501) = 1
HCF of 997, 380, 501 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 997, 380, 501 is 1.
Highest Common Factor of 997,380,501 is 1
Step 1: Since 997 > 380, we apply the division lemma to 997 and 380, to get
997 = 380 x 2 + 237
Step 2: Since the reminder 380 ≠ 0, we apply division lemma to 237 and 380, to get
380 = 237 x 1 + 143
Step 3: We consider the new divisor 237 and the new remainder 143, and apply the division lemma to get
237 = 143 x 1 + 94
We consider the new divisor 143 and the new remainder 94,and apply the division lemma to get
143 = 94 x 1 + 49
We consider the new divisor 94 and the new remainder 49,and apply the division lemma to get
94 = 49 x 1 + 45
We consider the new divisor 49 and the new remainder 45,and apply the division lemma to get
49 = 45 x 1 + 4
We consider the new divisor 45 and the new remainder 4,and apply the division lemma to get
45 = 4 x 11 + 1
We consider the new divisor 4 and the new remainder 1,and apply the division lemma to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 997 and 380 is 1
Notice that 1 = HCF(4,1) = HCF(45,4) = HCF(49,45) = HCF(94,49) = HCF(143,94) = HCF(237,143) = HCF(380,237) = HCF(997,380) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 501 > 1, we apply the division lemma to 501 and 1, to get
501 = 1 x 501 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 501 is 1
Notice that 1 = HCF(501,1) .
