HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 684, 722, 774 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 684, 722, 774 is 2 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 684, 722, 774 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 684, 722, 774 is 2.
HCF(684, 722, 774) = 2
HCF of 684, 722, 774 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 684, 722, 774 is 2.
Highest Common Factor of 684,722,774 is 2
Step 1: Since 722 > 684, we apply the division lemma to 722 and 684, to get
722 = 684 x 1 + 38
Step 2: Since the reminder 684 ≠ 0, we apply division lemma to 38 and 684, to get
684 = 38 x 18 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 38, the HCF of 684 and 722 is 38
Notice that 38 = HCF(684,38) = HCF(722,684) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 774 > 38, we apply the division lemma to 774 and 38, to get
774 = 38 x 20 + 14
Step 2: Since the reminder 38 ≠ 0, we apply division lemma to 14 and 38, to get
38 = 14 x 2 + 10
Step 3: We consider the new divisor 14 and the new remainder 10, and apply the division lemma to get
14 = 10 x 1 + 4
We consider the new divisor 10 and the new remainder 4,and apply the division lemma to get
10 = 4 x 2 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 38 and 774 is 2
Notice that 2 = HCF(4,2) = HCF(10,4) = HCF(14,10) = HCF(38,14) = HCF(774,38) .
