HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 440, 361, 157, 718 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 440, 361, 157, 718 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 440, 361, 157, 718 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 440, 361, 157, 718 is 1.
HCF(440, 361, 157, 718) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 440, 361, 157, 718 is 1.
Step 1: Since 440 > 361, we apply the division lemma to 440 and 361, to get
440 = 361 x 1 + 79
Step 2: Since the reminder 361 ≠ 0, we apply division lemma to 79 and 361, to get
361 = 79 x 4 + 45
Step 3: We consider the new divisor 79 and the new remainder 45, and apply the division lemma to get
79 = 45 x 1 + 34
We consider the new divisor 45 and the new remainder 34,and apply the division lemma to get
45 = 34 x 1 + 11
We consider the new divisor 34 and the new remainder 11,and apply the division lemma to get
34 = 11 x 3 + 1
We consider the new divisor 11 and the new remainder 1,and apply the division lemma to get
11 = 1 x 11 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 440 and 361 is 1
Notice that 1 = HCF(11,1) = HCF(34,11) = HCF(45,34) = HCF(79,45) = HCF(361,79) = HCF(440,361) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 157 > 1, we apply the division lemma to 157 and 1, to get
157 = 1 x 157 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 157 is 1
Notice that 1 = HCF(157,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 718 > 1, we apply the division lemma to 718 and 1, to get
718 = 1 x 718 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 718 is 1
Notice that 1 = HCF(718,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 440, 361, 157, 718?
Answer: HCF of 440, 361, 157, 718 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 440, 361, 157, 718 using Euclid's Algorithm?
Answer: For arbitrary numbers 440, 361, 157, 718 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
