HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 756, 147, 348 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 756, 147, 348 is 3 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 756, 147, 348 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 756, 147, 348 is 3.
HCF(756, 147, 348) = 3
HCF of 756, 147, 348 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 756, 147, 348 is 3.
Highest Common Factor of 756,147,348 is 3
Step 1: Since 756 > 147, we apply the division lemma to 756 and 147, to get
756 = 147 x 5 + 21
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 21 and 147, to get
147 = 21 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 21, the HCF of 756 and 147 is 21
Notice that 21 = HCF(147,21) = HCF(756,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 348 > 21, we apply the division lemma to 348 and 21, to get
348 = 21 x 16 + 12
Step 2: Since the reminder 21 ≠ 0, we apply division lemma to 12 and 21, to get
21 = 12 x 1 + 9
Step 3: 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 21 and 348 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(21,12) = HCF(348,21) .
