HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 354, 177, 147, 72 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 354, 177, 147, 72 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 354, 177, 147, 72 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 354, 177, 147, 72 is 3.
HCF(354, 177, 147, 72) = 3
HCF of 354, 177, 147, 72 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 354, 177, 147, 72 is 3.
Highest Common Factor of 354,177,147,72 is 3
Step 1: Since 354 > 177, we apply the division lemma to 354 and 177, to get
354 = 177 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 177, the HCF of 354 and 177 is 177
Notice that 177 = HCF(354,177) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 177 > 147, we apply the division lemma to 177 and 147, to get
177 = 147 x 1 + 30
Step 2: Since the reminder 147 ≠ 0, we apply division lemma to 30 and 147, to get
147 = 30 x 4 + 27
Step 3: We consider the new divisor 30 and the new remainder 27, and apply the division lemma to get
30 = 27 x 1 + 3
We consider the new divisor 27 and the new remainder 3, and apply the division lemma to get
27 = 3 x 9 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 177 and 147 is 3
Notice that 3 = HCF(27,3) = HCF(30,27) = HCF(147,30) = HCF(177,147) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 3, we apply the division lemma to 72 and 3, to get
72 = 3 x 24 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 3 and 72 is 3
Notice that 3 = HCF(72,3) .
