HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 292, 272, 647 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 292, 272, 647 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 292, 272, 647 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 292, 272, 647 is 1.
HCF(292, 272, 647) = 1
HCF of 292, 272, 647 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 292, 272, 647 is 1.
Highest Common Factor of 292,272,647 is 1
Step 1: Since 292 > 272, we apply the division lemma to 292 and 272, to get
292 = 272 x 1 + 20
Step 2: Since the reminder 272 ≠ 0, we apply division lemma to 20 and 272, to get
272 = 20 x 13 + 12
Step 3: We consider the new divisor 20 and the new remainder 12, and apply the division lemma to get
20 = 12 x 1 + 8
We consider the new divisor 12 and the new remainder 8,and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4,and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 292 and 272 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(20,12) = HCF(272,20) = HCF(292,272) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 647 > 4, we apply the division lemma to 647 and 4, to get
647 = 4 x 161 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: We consider the new divisor 3 and the new remainder 1, and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 647 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(647,4) .
