HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 604, 170, 541, 72 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 604, 170, 541, 72 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 604, 170, 541, 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 604, 170, 541, 72 is 1.
HCF(604, 170, 541, 72) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 604, 170, 541, 72 is 1.
Step 1: Since 604 > 170, we apply the division lemma to 604 and 170, to get
604 = 170 x 3 + 94
Step 2: Since the reminder 170 ≠ 0, we apply division lemma to 94 and 170, to get
170 = 94 x 1 + 76
Step 3: We consider the new divisor 94 and the new remainder 76, and apply the division lemma to get
94 = 76 x 1 + 18
We consider the new divisor 76 and the new remainder 18,and apply the division lemma to get
76 = 18 x 4 + 4
We consider the new divisor 18 and the new remainder 4,and apply the division lemma to get
18 = 4 x 4 + 2
We consider the new divisor 4 and the new remainder 2,and apply the division lemma to get
4 = 2 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 604 and 170 is 2
Notice that 2 = HCF(4,2) = HCF(18,4) = HCF(76,18) = HCF(94,76) = HCF(170,94) = HCF(604,170) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 541 > 2, we apply the division lemma to 541 and 2, to get
541 = 2 x 270 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 541 is 1
Notice that 1 = HCF(2,1) = HCF(541,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 72 > 1, we apply the division lemma to 72 and 1, to get
72 = 1 x 72 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 72 is 1
Notice that 1 = HCF(72,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 604, 170, 541, 72?
Answer: HCF of 604, 170, 541, 72 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 604, 170, 541, 72 using Euclid's Algorithm?
