HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 723, 398, 624 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 723, 398, 624 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 723, 398, 624 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 723, 398, 624 is 1.
HCF(723, 398, 624) = 1
HCF of 723, 398, 624 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 723, 398, 624 is 1.
Highest Common Factor of 723,398,624 is 1
Step 1: Since 723 > 398, we apply the division lemma to 723 and 398, to get
723 = 398 x 1 + 325
Step 2: Since the reminder 398 ≠ 0, we apply division lemma to 325 and 398, to get
398 = 325 x 1 + 73
Step 3: We consider the new divisor 325 and the new remainder 73, and apply the division lemma to get
325 = 73 x 4 + 33
We consider the new divisor 73 and the new remainder 33,and apply the division lemma to get
73 = 33 x 2 + 7
We consider the new divisor 33 and the new remainder 7,and apply the division lemma to get
33 = 7 x 4 + 5
We consider the new divisor 7 and the new remainder 5,and apply the division lemma to get
7 = 5 x 1 + 2
We consider the new divisor 5 and the new remainder 2,and apply the division lemma to get
5 = 2 x 2 + 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 723 and 398 is 1
Notice that 1 = HCF(2,1) = HCF(5,2) = HCF(7,5) = HCF(33,7) = HCF(73,33) = HCF(325,73) = HCF(398,325) = HCF(723,398) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 624 > 1, we apply the division lemma to 624 and 1, to get
624 = 1 x 624 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 624 is 1
Notice that 1 = HCF(624,1) .
