HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 261, 629, 524 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 261, 629, 524 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 624, 261, 629, 524 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 624, 261, 629, 524 is 1.
HCF(624, 261, 629, 524) = 1
HCF of 624, 261, 629, 524 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 624, 261, 629, 524 is 1.
Highest Common Factor of 624,261,629,524 is 1
Step 1: Since 624 > 261, we apply the division lemma to 624 and 261, to get
624 = 261 x 2 + 102
Step 2: Since the reminder 261 ≠ 0, we apply division lemma to 102 and 261, to get
261 = 102 x 2 + 57
Step 3: We consider the new divisor 102 and the new remainder 57, and apply the division lemma to get
102 = 57 x 1 + 45
We consider the new divisor 57 and the new remainder 45,and apply the division lemma to get
57 = 45 x 1 + 12
We consider the new divisor 45 and the new remainder 12,and apply the division lemma to get
45 = 12 x 3 + 9
We consider the new divisor 12 and the new remainder 9,and apply the division lemma to get
12 = 9 x 1 + 3
We consider the new divisor 9 and the new remainder 3,and apply the division lemma to get
9 = 3 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 624 and 261 is 3
Notice that 3 = HCF(9,3) = HCF(12,9) = HCF(45,12) = HCF(57,45) = HCF(102,57) = HCF(261,102) = HCF(624,261) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 629 > 3, we apply the division lemma to 629 and 3, to get
629 = 3 x 209 + 2
Step 2: Since the reminder 3 ≠ 0, we apply division lemma to 2 and 3, to get
3 = 2 x 1 + 1
Step 3: We consider the new divisor 2 and the new remainder 1, and apply the division lemma 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 3 and 629 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(629,3) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 524 > 1, we apply the division lemma to 524 and 1, to get
524 = 1 x 524 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 524 is 1
Notice that 1 = HCF(524,1) .
