HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 774, 423, 762 i.e. 3 the largest integer that leaves a remainder zero for all numbers.
HCF of 774, 423, 762 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 774, 423, 762 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, 423, 762 is 3.
HCF(774, 423, 762) = 3
HCF of 774, 423, 762 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 774, 423, 762 is 3.
Highest Common Factor of 774,423,762 is 3
Step 1: Since 774 > 423, we apply the division lemma to 774 and 423, to get
774 = 423 x 1 + 351
Step 2: Since the reminder 423 ≠ 0, we apply division lemma to 351 and 423, to get
423 = 351 x 1 + 72
Step 3: We consider the new divisor 351 and the new remainder 72, and apply the division lemma to get
351 = 72 x 4 + 63
We consider the new divisor 72 and the new remainder 63,and apply the division lemma to get
72 = 63 x 1 + 9
We consider the new divisor 63 and the new remainder 9,and apply the division lemma to get
63 = 9 x 7 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 9, the HCF of 774 and 423 is 9
Notice that 9 = HCF(63,9) = HCF(72,63) = HCF(351,72) = HCF(423,351) = HCF(774,423) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 762 > 9, we apply the division lemma to 762 and 9, to get
762 = 9 x 84 + 6
Step 2: Since the reminder 9 ≠ 0, we apply division lemma to 6 and 9, to get
9 = 6 x 1 + 3
Step 3: We consider the new divisor 6 and the new remainder 3, and apply the division lemma to get
6 = 3 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 9 and 762 is 3
Notice that 3 = HCF(6,3) = HCF(9,6) = HCF(762,9) .
