HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 632, 620, 745 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 632, 620, 745 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 632, 620, 745 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 632, 620, 745 is 1.
HCF(632, 620, 745) = 1
HCF of 632, 620, 745 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 632, 620, 745 is 1.
Highest Common Factor of 632,620,745 is 1
Step 1: Since 632 > 620, we apply the division lemma to 632 and 620, to get
632 = 620 x 1 + 12
Step 2: Since the reminder 620 ≠ 0, we apply division lemma to 12 and 620, to get
620 = 12 x 51 + 8
Step 3: We consider the new divisor 12 and the new remainder 8, and apply the division lemma to get
12 = 8 x 1 + 4
We consider the new divisor 8 and the new remainder 4, and apply the division lemma to get
8 = 4 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 632 and 620 is 4
Notice that 4 = HCF(8,4) = HCF(12,8) = HCF(620,12) = HCF(632,620) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 745 > 4, we apply the division lemma to 745 and 4, to get
745 = 4 x 186 + 1
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 1 and 4, to get
4 = 1 x 4 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 4 and 745 is 1
Notice that 1 = HCF(4,1) = HCF(745,4) .
