HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 76, 684, 720 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 76, 684, 720 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 76, 684, 720 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 76, 684, 720 is 4.
HCF(76, 684, 720) = 4
HCF of 76, 684, 720 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 76, 684, 720 is 4.
Highest Common Factor of 76,684,720 is 4
Step 1: Since 684 > 76, we apply the division lemma to 684 and 76, to get
684 = 76 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 76, the HCF of 76 and 684 is 76
Notice that 76 = HCF(684,76) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 720 > 76, we apply the division lemma to 720 and 76, to get
720 = 76 x 9 + 36
Step 2: Since the reminder 76 ≠ 0, we apply division lemma to 36 and 76, to get
76 = 36 x 2 + 4
Step 3: We consider the new divisor 36 and the new remainder 4, and apply the division lemma to get
36 = 4 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 76 and 720 is 4
Notice that 4 = HCF(36,4) = HCF(76,36) = HCF(720,76) .
