HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 636, 572 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 636, 572 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 342, 636, 572 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 342, 636, 572 is 2.
HCF(342, 636, 572) = 2
HCF of 342, 636, 572 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 342, 636, 572 is 2.
Highest Common Factor of 342,636,572 is 2
Step 1: Since 636 > 342, we apply the division lemma to 636 and 342, to get
636 = 342 x 1 + 294
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 294 and 342, to get
342 = 294 x 1 + 48
Step 3: We consider the new divisor 294 and the new remainder 48, and apply the division lemma to get
294 = 48 x 6 + 6
We consider the new divisor 48 and the new remainder 6, and apply the division lemma to get
48 = 6 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 6, the HCF of 342 and 636 is 6
Notice that 6 = HCF(48,6) = HCF(294,48) = HCF(342,294) = HCF(636,342) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 572 > 6, we apply the division lemma to 572 and 6, to get
572 = 6 x 95 + 2
Step 2: Since the reminder 6 ≠ 0, we apply division lemma to 2 and 6, to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 6 and 572 is 2
Notice that 2 = HCF(6,2) = HCF(572,6) .
