HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 721, 624, 582 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 721, 624, 582 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 721, 624, 582 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 721, 624, 582 is 1.
HCF(721, 624, 582) = 1
HCF of 721, 624, 582 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 721, 624, 582 is 1.
Highest Common Factor of 721,624,582 is 1
Step 1: Since 721 > 624, we apply the division lemma to 721 and 624, to get
721 = 624 x 1 + 97
Step 2: Since the reminder 624 ≠ 0, we apply division lemma to 97 and 624, to get
624 = 97 x 6 + 42
Step 3: We consider the new divisor 97 and the new remainder 42, and apply the division lemma to get
97 = 42 x 2 + 13
We consider the new divisor 42 and the new remainder 13,and apply the division lemma to get
42 = 13 x 3 + 3
We consider the new divisor 13 and the new remainder 3,and apply the division lemma to get
13 = 3 x 4 + 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 721 and 624 is 1
Notice that 1 = HCF(3,1) = HCF(13,3) = HCF(42,13) = HCF(97,42) = HCF(624,97) = HCF(721,624) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 582 > 1, we apply the division lemma to 582 and 1, to get
582 = 1 x 582 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 582 is 1
Notice that 1 = HCF(582,1) .
