HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 625, 920, 453, 376 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 625, 920, 453, 376 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 625, 920, 453, 376 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 625, 920, 453, 376 is 1.
HCF(625, 920, 453, 376) = 1
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 625, 920, 453, 376 is 1.
Step 1: Since 920 > 625, we apply the division lemma to 920 and 625, to get
920 = 625 x 1 + 295
Step 2: Since the reminder 625 ≠ 0, we apply division lemma to 295 and 625, to get
625 = 295 x 2 + 35
Step 3: We consider the new divisor 295 and the new remainder 35, and apply the division lemma to get
295 = 35 x 8 + 15
We consider the new divisor 35 and the new remainder 15,and apply the division lemma to get
35 = 15 x 2 + 5
We consider the new divisor 15 and the new remainder 5,and apply the division lemma to get
15 = 5 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 625 and 920 is 5
Notice that 5 = HCF(15,5) = HCF(35,15) = HCF(295,35) = HCF(625,295) = HCF(920,625) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 453 > 5, we apply the division lemma to 453 and 5, to get
453 = 5 x 90 + 3
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 3 and 5, to get
5 = 3 x 1 + 2
Step 3: We consider the new divisor 3 and the new remainder 2, and apply the division lemma to get
3 = 2 x 1 + 1
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 5 and 453 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(5,3) = HCF(453,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 376 > 1, we apply the division lemma to 376 and 1, to get
376 = 1 x 376 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 376 is 1
Notice that 1 = HCF(376,1) .
