HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 745, 447, 635 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 745, 447, 635 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 745, 447, 635 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 745, 447, 635 is 1.
HCF(745, 447, 635) = 1
HCF of 745, 447, 635 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 745, 447, 635 is 1.
Highest Common Factor of 745,447,635 is 1
Step 1: Since 745 > 447, we apply the division lemma to 745 and 447, to get
745 = 447 x 1 + 298
Step 2: Since the reminder 447 ≠ 0, we apply division lemma to 298 and 447, to get
447 = 298 x 1 + 149
Step 3: We consider the new divisor 298 and the new remainder 149, and apply the division lemma to get
298 = 149 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 149, the HCF of 745 and 447 is 149
Notice that 149 = HCF(298,149) = HCF(447,298) = HCF(745,447) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 635 > 149, we apply the division lemma to 635 and 149, to get
635 = 149 x 4 + 39
Step 2: Since the reminder 149 ≠ 0, we apply division lemma to 39 and 149, to get
149 = 39 x 3 + 32
Step 3: We consider the new divisor 39 and the new remainder 32, and apply the division lemma to get
39 = 32 x 1 + 7
We consider the new divisor 32 and the new remainder 7,and apply the division lemma to get
32 = 7 x 4 + 4
We consider the new divisor 7 and the new remainder 4,and apply the division lemma to get
7 = 4 x 1 + 3
We consider the new divisor 4 and the new remainder 3,and apply the division lemma to get
4 = 3 x 1 + 1
We consider the new divisor 3 and the new remainder 1,and apply the division lemma to get
3 = 1 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 149 and 635 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(7,4) = HCF(32,7) = HCF(39,32) = HCF(149,39) = HCF(635,149) .
