HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 434, 759 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 434, 759 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 774, 434, 759 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 774, 434, 759 is 1.
HCF(774, 434, 759) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 434, 759 is 1.
Step 1: Since 774 > 434, we apply the division lemma to 774 and 434, to get
774 = 434 x 1 + 340
Step 2: Since the reminder 434 ≠ 0, we apply division lemma to 340 and 434, to get
434 = 340 x 1 + 94
Step 3: We consider the new divisor 340 and the new remainder 94, and apply the division lemma to get
340 = 94 x 3 + 58
We consider the new divisor 94 and the new remainder 58,and apply the division lemma to get
94 = 58 x 1 + 36
We consider the new divisor 58 and the new remainder 36,and apply the division lemma to get
58 = 36 x 1 + 22
We consider the new divisor 36 and the new remainder 22,and apply the division lemma to get
36 = 22 x 1 + 14
We consider the new divisor 22 and the new remainder 14,and apply the division lemma to get
22 = 14 x 1 + 8
We consider the new divisor 14 and the new remainder 8,and apply the division lemma to get
14 = 8 x 1 + 6
We consider the new divisor 8 and the new remainder 6,and apply the division lemma to get
8 = 6 x 1 + 2
We consider the new divisor 6 and the new remainder 2,and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 774 and 434 is 2
Notice that 2 = HCF(6,2) = HCF(8,6) = HCF(14,8) = HCF(22,14) = HCF(36,22) = HCF(58,36) = HCF(94,58) = HCF(340,94) = HCF(434,340) = HCF(774,434) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 759 > 2, we apply the division lemma to 759 and 2, to get
759 = 2 x 379 + 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 759 is 1
Notice that 1 = HCF(2,1) = HCF(759,2) .
Here are some samples of HCF using Euclid's Algorithm calculations.

2. what is the HCF of 774, 434, 759?
Answer: HCF of 774, 434, 759 is 1 the largest number that divides all the numbers leaving a remainder zero.
3. How to find HCF of 774, 434, 759 using Euclid's Algorithm?
Answer: For arbitrary numbers 774, 434, 759 apply Euclid’s Division Lemma in succession until you obtain a remainder zero. HCF is the remainder in the last but one step.
