HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 677, 420, 962, 754 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 677, 420, 962, 754 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 677, 420, 962, 754 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 677, 420, 962, 754 is 1.
HCF(677, 420, 962, 754) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 677, 420, 962, 754 is 1.
Step 1: Since 677 > 420, we apply the division lemma to 677 and 420, to get
677 = 420 x 1 + 257
Step 2: Since the reminder 420 ≠ 0, we apply division lemma to 257 and 420, to get
420 = 257 x 1 + 163
Step 3: We consider the new divisor 257 and the new remainder 163, and apply the division lemma to get
257 = 163 x 1 + 94
We consider the new divisor 163 and the new remainder 94,and apply the division lemma to get
163 = 94 x 1 + 69
We consider the new divisor 94 and the new remainder 69,and apply the division lemma to get
94 = 69 x 1 + 25
We consider the new divisor 69 and the new remainder 25,and apply the division lemma to get
69 = 25 x 2 + 19
We consider the new divisor 25 and the new remainder 19,and apply the division lemma to get
25 = 19 x 1 + 6
We consider the new divisor 19 and the new remainder 6,and apply the division lemma to get
19 = 6 x 3 + 1
We consider the new divisor 6 and the new remainder 1,and apply the division lemma to get
6 = 1 x 6 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 677 and 420 is 1
Notice that 1 = HCF(6,1) = HCF(19,6) = HCF(25,19) = HCF(69,25) = HCF(94,69) = HCF(163,94) = HCF(257,163) = HCF(420,257) = HCF(677,420) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 962 > 1, we apply the division lemma to 962 and 1, to get
962 = 1 x 962 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 962 is 1
Notice that 1 = HCF(962,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 754 > 1, we apply the division lemma to 754 and 1, to get
754 = 1 x 754 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 754 is 1
Notice that 1 = HCF(754,1) .
Here are some samples of HCF using Euclid's Algorithm calculations.
