HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 761, 406, 469, 220 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 761, 406, 469, 220 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 761, 406, 469, 220 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 761, 406, 469, 220 is 1.
HCF(761, 406, 469, 220) = 1
HCF of 761, 406, 469, 220 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 761, 406, 469, 220 is 1.
Highest Common Factor of 761,406,469,220 is 1
Step 1: Since 761 > 406, we apply the division lemma to 761 and 406, to get
761 = 406 x 1 + 355
Step 2: Since the reminder 406 ≠ 0, we apply division lemma to 355 and 406, to get
406 = 355 x 1 + 51
Step 3: We consider the new divisor 355 and the new remainder 51, and apply the division lemma to get
355 = 51 x 6 + 49
We consider the new divisor 51 and the new remainder 49,and apply the division lemma to get
51 = 49 x 1 + 2
We consider the new divisor 49 and the new remainder 2,and apply the division lemma to get
49 = 2 x 24 + 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 761 and 406 is 1
Notice that 1 = HCF(2,1) = HCF(49,2) = HCF(51,49) = HCF(355,51) = HCF(406,355) = HCF(761,406) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 469 > 1, we apply the division lemma to 469 and 1, to get
469 = 1 x 469 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 469 is 1
Notice that 1 = HCF(469,1) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 220 > 1, we apply the division lemma to 220 and 1, to get
220 = 1 x 220 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 220 is 1
Notice that 1 = HCF(220,1) .
