HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 12, 40, 720, 764 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 12, 40, 720, 764 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 12, 40, 720, 764 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 12, 40, 720, 764 is 4.
HCF(12, 40, 720, 764) = 4
HCF of 12, 40, 720, 764 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 12, 40, 720, 764 is 4.
Highest Common Factor of 12,40,720,764 is 4
Step 1: Since 40 > 12, we apply the division lemma to 40 and 12, to get
40 = 12 x 3 + 4
Step 2: Since the reminder 12 ≠ 0, we apply division lemma to 4 and 12, to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 12 and 40 is 4
Notice that 4 = HCF(12,4) = HCF(40,12) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 4, we apply the division lemma to 720 and 4, to get
720 = 4 x 180 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 720 is 4
Notice that 4 = HCF(720,4) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 764 > 4, we apply the division lemma to 764 and 4, to get
764 = 4 x 191 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 764 is 4
Notice that 4 = HCF(764,4) .
