HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 507, 645, 632 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 507, 645, 632 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 507, 645, 632 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 507, 645, 632 is 1.
HCF(507, 645, 632) = 1
HCF of 507, 645, 632 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 507, 645, 632 is 1.
Highest Common Factor of 507,645,632 is 1
Step 1: Since 645 > 507, we apply the division lemma to 645 and 507, to get
645 = 507 x 1 + 138
Step 2: Since the reminder 507 ≠ 0, we apply division lemma to 138 and 507, to get
507 = 138 x 3 + 93
Step 3: We consider the new divisor 138 and the new remainder 93, and apply the division lemma to get
138 = 93 x 1 + 45
We consider the new divisor 93 and the new remainder 45,and apply the division lemma to get
93 = 45 x 2 + 3
We consider the new divisor 45 and the new remainder 3,and apply the division lemma to get
45 = 3 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 3, the HCF of 507 and 645 is 3
Notice that 3 = HCF(45,3) = HCF(93,45) = HCF(138,93) = HCF(507,138) = HCF(645,507) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 632 > 3, we apply the division lemma to 632 and 3, to get
632 = 3 x 210 + 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 632 is 1
Notice that 1 = HCF(2,1) = HCF(3,2) = HCF(632,3) .
