HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 542, 628, 388 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 542, 628, 388 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 542, 628, 388 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 542, 628, 388 is 2.
HCF(542, 628, 388) = 2
HCF of 542, 628, 388 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 542, 628, 388 is 2.
Highest Common Factor of 542,628,388 is 2
Step 1: Since 628 > 542, we apply the division lemma to 628 and 542, to get
628 = 542 x 1 + 86
Step 2: Since the reminder 542 ≠ 0, we apply division lemma to 86 and 542, to get
542 = 86 x 6 + 26
Step 3: We consider the new divisor 86 and the new remainder 26, and apply the division lemma to get
86 = 26 x 3 + 8
We consider the new divisor 26 and the new remainder 8,and apply the division lemma to get
26 = 8 x 3 + 2
We consider the new divisor 8 and the new remainder 2,and apply the division lemma to get
8 = 2 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 542 and 628 is 2
Notice that 2 = HCF(8,2) = HCF(26,8) = HCF(86,26) = HCF(542,86) = HCF(628,542) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 388 > 2, we apply the division lemma to 388 and 2, to get
388 = 2 x 194 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 2 and 388 is 2
Notice that 2 = HCF(388,2) .
