HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 342, 651, 173, 527 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 342, 651, 173, 527 is 1 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, 651, 173, 527 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, 651, 173, 527 is 1.
HCF(342, 651, 173, 527) = 1
HCF of 342, 651, 173, 527 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, 651, 173, 527 is 1.
Highest Common Factor of 342,651,173,527 is 1
Step 1: Since 651 > 342, we apply the division lemma to 651 and 342, to get
651 = 342 x 1 + 309
Step 2: Since the reminder 342 ≠ 0, we apply division lemma to 309 and 342, to get
342 = 309 x 1 + 33
Step 3: We consider the new divisor 309 and the new remainder 33, and apply the division lemma to get
309 = 33 x 9 + 12
We consider the new divisor 33 and the new remainder 12,and apply the division lemma to get
33 = 12 x 2 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 342 and 651 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(33,12) = HCF(309,33) = HCF(342,309) = HCF(651,342) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 173 > 3, we apply the division lemma to 173 and 3, to get
173 = 3 x 57 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma to get
2 = 1 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 3 and 173 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(173,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 527 > 1, we apply the division lemma to 527 and 1, to get
527 = 1 x 527 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 527 is 1
Notice that 1 = HCF(527,1) .
