HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 624, 349, 728, 37 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 624, 349, 728, 37 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, 349, 728, 37 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, 349, 728, 37 is 1.
HCF(624, 349, 728, 37) = 1
HCF of 624, 349, 728, 37 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, 349, 728, 37 is 1.
Highest Common Factor of 624,349,728,37 is 1
Step 1: Since 624 > 349, we apply the division lemma to 624 and 349, to get
624 = 349 x 1 + 275
Step 2: Since the reminder 349 ≠ 0, we apply division lemma to 275 and 349, to get
349 = 275 x 1 + 74
Step 3: We consider the new divisor 275 and the new remainder 74, and apply the division lemma to get
275 = 74 x 3 + 53
We consider the new divisor 74 and the new remainder 53,and apply the division lemma to get
74 = 53 x 1 + 21
We consider the new divisor 53 and the new remainder 21,and apply the division lemma to get
53 = 21 x 2 + 11
We consider the new divisor 21 and the new remainder 11,and apply the division lemma to get
21 = 11 x 1 + 10
We consider the new divisor 11 and the new remainder 10,and apply the division lemma to get
11 = 10 x 1 + 1
We consider the new divisor 10 and the new remainder 1,and apply the division lemma to get
10 = 1 x 10 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 624 and 349 is 1
Notice that 1 = HCF(10,1) = HCF(11,10) = HCF(21,11) = HCF(53,21) = HCF(74,53) = HCF(275,74) = HCF(349,275) = HCF(624,349) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 728 > 1, we apply the division lemma to 728 and 1, to get
728 = 1 x 728 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 728 is 1
Notice that 1 = HCF(728,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 37 > 1, we apply the division lemma to 37 and 1, to get
37 = 1 x 37 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 37 is 1
Notice that 1 = HCF(37,1) .
