HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 388, 628, 684 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 388, 628, 684 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 388, 628, 684 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 388, 628, 684 is 4.
HCF(388, 628, 684) = 4
HCF of 388, 628, 684 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 388, 628, 684 is 4.
Highest Common Factor of 388,628,684 is 4
Step 1: Since 628 > 388, we apply the division lemma to 628 and 388, to get
628 = 388 x 1 + 240
Step 2: Since the reminder 388 ≠ 0, we apply division lemma to 240 and 388, to get
388 = 240 x 1 + 148
Step 3: We consider the new divisor 240 and the new remainder 148, and apply the division lemma to get
240 = 148 x 1 + 92
We consider the new divisor 148 and the new remainder 92,and apply the division lemma to get
148 = 92 x 1 + 56
We consider the new divisor 92 and the new remainder 56,and apply the division lemma to get
92 = 56 x 1 + 36
We consider the new divisor 56 and the new remainder 36,and apply the division lemma to get
56 = 36 x 1 + 20
We consider the new divisor 36 and the new remainder 20,and apply the division lemma to get
36 = 20 x 1 + 16
We consider the new divisor 20 and the new remainder 16,and apply the division lemma to get
20 = 16 x 1 + 4
We consider the new divisor 16 and the new remainder 4,and apply the division lemma to get
16 = 4 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 388 and 628 is 4
Notice that 4 = HCF(16,4) = HCF(20,16) = HCF(36,20) = HCF(56,36) = HCF(92,56) = HCF(148,92) = HCF(240,148) = HCF(388,240) = HCF(628,388) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 684 > 4, we apply the division lemma to 684 and 4, to get
684 = 4 x 171 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 4 and 684 is 4
Notice that 4 = HCF(684,4) .
