HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 864, 232, 720, 180 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 864, 232, 720, 180 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 864, 232, 720, 180 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 864, 232, 720, 180 is 4.
HCF(864, 232, 720, 180) = 4
HCF of 864, 232, 720, 180 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 864, 232, 720, 180 is 4.
Highest Common Factor of 864,232,720,180 is 4
Step 1: Since 864 > 232, we apply the division lemma to 864 and 232, to get
864 = 232 x 3 + 168
Step 2: Since the reminder 232 ≠ 0, we apply division lemma to 168 and 232, to get
232 = 168 x 1 + 64
Step 3: We consider the new divisor 168 and the new remainder 64, and apply the division lemma to get
168 = 64 x 2 + 40
We consider the new divisor 64 and the new remainder 40,and apply the division lemma to get
64 = 40 x 1 + 24
We consider the new divisor 40 and the new remainder 24,and apply the division lemma to get
40 = 24 x 1 + 16
We consider the new divisor 24 and the new remainder 16,and apply the division lemma to get
24 = 16 x 1 + 8
We consider the new divisor 16 and the new remainder 8,and apply the division lemma to get
16 = 8 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 864 and 232 is 8
Notice that 8 = HCF(16,8) = HCF(24,16) = HCF(40,24) = HCF(64,40) = HCF(168,64) = HCF(232,168) = HCF(864,232) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 8, we apply the division lemma to 720 and 8, to get
720 = 8 x 90 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 8, the HCF of 8 and 720 is 8
Notice that 8 = HCF(720,8) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 180 > 8, we apply the division lemma to 180 and 8, to get
180 = 8 x 22 + 4
Step 2: Since the reminder 8 ≠ 0, we apply division lemma to 4 and 8, 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 8 and 180 is 4
Notice that 4 = HCF(8,4) = HCF(180,8) .
