HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 724, 468 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 724, 468 is 4 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 724, 468 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 724, 468 is 4.
HCF(724, 468) = 4
HCF of 724, 468 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 724, 468 is 4.
Highest Common Factor of 724,468 is 4
Step 1: Since 724 > 468, we apply the division lemma to 724 and 468, to get
724 = 468 x 1 + 256
Step 2: Since the reminder 468 ≠ 0, we apply division lemma to 256 and 468, to get
468 = 256 x 1 + 212
Step 3: We consider the new divisor 256 and the new remainder 212, and apply the division lemma to get
256 = 212 x 1 + 44
We consider the new divisor 212 and the new remainder 44,and apply the division lemma to get
212 = 44 x 4 + 36
We consider the new divisor 44 and the new remainder 36,and apply the division lemma to get
44 = 36 x 1 + 8
We consider the new divisor 36 and the new remainder 8,and apply the division lemma to get
36 = 8 x 4 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 724 and 468 is 4
Notice that 4 = HCF(8,4) = HCF(36,8) = HCF(44,36) = HCF(212,44) = HCF(256,212) = HCF(468,256) = HCF(724,468) .
