HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 605, 530, 651, 660 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 605, 530, 651, 660 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 605, 530, 651, 660 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 605, 530, 651, 660 is 1.
HCF(605, 530, 651, 660) = 1
HCF of 605, 530, 651, 660 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 605, 530, 651, 660 is 1.
Highest Common Factor of 605,530,651,660 is 1
Step 1: Since 605 > 530, we apply the division lemma to 605 and 530, to get
605 = 530 x 1 + 75
Step 2: Since the reminder 530 ≠ 0, we apply division lemma to 75 and 530, to get
530 = 75 x 7 + 5
Step 3: We consider the new divisor 75 and the new remainder 5, and apply the division lemma to get
75 = 5 x 15 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 5, the HCF of 605 and 530 is 5
Notice that 5 = HCF(75,5) = HCF(530,75) = HCF(605,530) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 651 > 5, we apply the division lemma to 651 and 5, to get
651 = 5 x 130 + 1
Step 2: Since the reminder 5 ≠ 0, we apply division lemma to 1 and 5, to get
5 = 1 x 5 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 5 and 651 is 1
Notice that 1 = HCF(5,1) = HCF(651,5) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 660 > 1, we apply the division lemma to 660 and 1, to get
660 = 1 x 660 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 660 is 1
Notice that 1 = HCF(660,1) .
