HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 432, 821, 93 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 432, 821, 93 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 432, 821, 93 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 432, 821, 93 is 1.
HCF(432, 821, 93) = 1
HCF of 432, 821, 93 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 432, 821, 93 is 1.
Highest Common Factor of 432,821,93 is 1
Step 1: Since 821 > 432, we apply the division lemma to 821 and 432, to get
821 = 432 x 1 + 389
Step 2: Since the reminder 432 ≠ 0, we apply division lemma to 389 and 432, to get
432 = 389 x 1 + 43
Step 3: We consider the new divisor 389 and the new remainder 43, and apply the division lemma to get
389 = 43 x 9 + 2
We consider the new divisor 43 and the new remainder 2,and apply the division lemma to get
43 = 2 x 21 + 1
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 432 and 821 is 1
Notice that 1 = HCF(2,1) = HCF(43,2) = HCF(389,43) = HCF(432,389) = HCF(821,432) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 93 > 1, we apply the division lemma to 93 and 1, to get
93 = 1 x 93 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 93 is 1
Notice that 1 = HCF(93,1) .
