HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 462, 667, 973, 421 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 462, 667, 973, 421 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 462, 667, 973, 421 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 462, 667, 973, 421 is 1.
HCF(462, 667, 973, 421) = 1
HCF of 462, 667, 973, 421 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 462, 667, 973, 421 is 1.
Highest Common Factor of 462,667,973,421 is 1
Step 1: Since 667 > 462, we apply the division lemma to 667 and 462, to get
667 = 462 x 1 + 205
Step 2: Since the reminder 462 ≠ 0, we apply division lemma to 205 and 462, to get
462 = 205 x 2 + 52
Step 3: We consider the new divisor 205 and the new remainder 52, and apply the division lemma to get
205 = 52 x 3 + 49
We consider the new divisor 52 and the new remainder 49,and apply the division lemma to get
52 = 49 x 1 + 3
We consider the new divisor 49 and the new remainder 3,and apply the division lemma to get
49 = 3 x 16 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 462 and 667 is 1
Notice that 1 = HCF(3,1) = HCF(49,3) = HCF(52,49) = HCF(205,52) = HCF(462,205) = HCF(667,462) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 973 > 1, we apply the division lemma to 973 and 1, to get
973 = 1 x 973 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 973 is 1
Notice that 1 = HCF(973,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 421 > 1, we apply the division lemma to 421 and 1, to get
421 = 1 x 421 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 421 is 1
Notice that 1 = HCF(421,1) .
