HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 220, 456, 659 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 220, 456, 659 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 220, 456, 659 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 220, 456, 659 is 1.
HCF(220, 456, 659) = 1
HCF of 220, 456, 659 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 220, 456, 659 is 1.
Highest Common Factor of 220,456,659 is 1
Step 1: Since 456 > 220, we apply the division lemma to 456 and 220, to get
456 = 220 x 2 + 16
Step 2: Since the reminder 220 ≠ 0, we apply division lemma to 16 and 220, to get
220 = 16 x 13 + 12
Step 3: We consider the new divisor 16 and the new remainder 12, and apply the division lemma to get
16 = 12 x 1 + 4
We consider the new divisor 12 and the new remainder 4, and apply the division lemma to get
12 = 4 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 4, the HCF of 220 and 456 is 4
Notice that 4 = HCF(12,4) = HCF(16,12) = HCF(220,16) = HCF(456,220) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 659 > 4, we apply the division lemma to 659 and 4, to get
659 = 4 x 164 + 3
Step 2: Since the reminder 4 ≠ 0, we apply division lemma to 3 and 4, to get
4 = 3 x 1 + 1
Step 3: 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 4 and 659 is 1
Notice that 1 = HCF(3,1) = HCF(4,3) = HCF(659,4) .
