HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 438, 292, 220 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 438, 292, 220 is 2 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 438, 292, 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 438, 292, 220 is 2.
HCF(438, 292, 220) = 2
HCF of 438, 292, 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 438, 292, 220 is 2.
Highest Common Factor of 438,292,220 is 2
Step 1: Since 438 > 292, we apply the division lemma to 438 and 292, to get
438 = 292 x 1 + 146
Step 2: Since the reminder 292 ≠ 0, we apply division lemma to 146 and 292, to get
292 = 146 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 146, the HCF of 438 and 292 is 146
Notice that 146 = HCF(292,146) = HCF(438,292) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 220 > 146, we apply the division lemma to 220 and 146, to get
220 = 146 x 1 + 74
Step 2: Since the reminder 146 ≠ 0, we apply division lemma to 74 and 146, to get
146 = 74 x 1 + 72
Step 3: We consider the new divisor 74 and the new remainder 72, and apply the division lemma to get
74 = 72 x 1 + 2
We consider the new divisor 72 and the new remainder 2, and apply the division lemma to get
72 = 2 x 36 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 146 and 220 is 2
Notice that 2 = HCF(72,2) = HCF(74,72) = HCF(146,74) = HCF(220,146) .
