HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 128, 272, 452 i.e. 4 the largest integer that leaves a remainder zero for all numbers.
HCF of 128, 272, 452 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 128, 272, 452 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 128, 272, 452 is 4.
HCF(128, 272, 452) = 4
HCF of 128, 272, 452 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 128, 272, 452 is 4.
Highest Common Factor of 128,272,452 is 4
Step 1: Since 272 > 128, we apply the division lemma to 272 and 128, to get
272 = 128 x 2 + 16
Step 2: Since the reminder 128 ≠ 0, we apply division lemma to 16 and 128, to get
128 = 16 x 8 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 16, the HCF of 128 and 272 is 16
Notice that 16 = HCF(128,16) = HCF(272,128) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 452 > 16, we apply the division lemma to 452 and 16, to get
452 = 16 x 28 + 4
Step 2: Since the reminder 16 ≠ 0, we apply division lemma to 4 and 16, 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 16 and 452 is 4
Notice that 4 = HCF(16,4) = HCF(452,16) .
