HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 720, 284, 976 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 720, 284, 976 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 720, 284, 976 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 720, 284, 976 is 4.
HCF(720, 284, 976) = 4
HCF of 720, 284, 976 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 720, 284, 976 is 4.
Highest Common Factor of 720,284,976 is 4
Step 1: Since 720 > 284, we apply the division lemma to 720 and 284, to get
720 = 284 x 2 + 152
Step 2: Since the reminder 284 ≠ 0, we apply division lemma to 152 and 284, to get
284 = 152 x 1 + 132
Step 3: We consider the new divisor 152 and the new remainder 132, and apply the division lemma to get
152 = 132 x 1 + 20
We consider the new divisor 132 and the new remainder 20,and apply the division lemma to get
132 = 20 x 6 + 12
We consider the new divisor 20 and the new remainder 12,and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 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 720 and 284 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(132,20) = HCF(152,132) = HCF(284,152) = HCF(720,284) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 976 > 4, we apply the division lemma to 976 and 4, to get
976 = 4 x 244 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 976 is 4
Notice that 4 = HCF(976,4) .
