HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 298, 426, 279, 654 i.e. 1 the largest integer that leaves a remainder zero for all numbers.
HCF of 298, 426, 279, 654 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 298, 426, 279, 654 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 298, 426, 279, 654 is 1.
HCF(298, 426, 279, 654) = 1
HCF of 298, 426, 279, 654 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 298, 426, 279, 654 is 1.
Highest Common Factor of 298,426,279,654 is 1
Step 1: Since 426 > 298, we apply the division lemma to 426 and 298, to get
426 = 298 x 1 + 128
Step 2: Since the reminder 298 ≠ 0, we apply division lemma to 128 and 298, to get
298 = 128 x 2 + 42
Step 3: We consider the new divisor 128 and the new remainder 42, and apply the division lemma to get
128 = 42 x 3 + 2
We consider the new divisor 42 and the new remainder 2, and apply the division lemma to get
42 = 2 x 21 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 298 and 426 is 2
Notice that 2 = HCF(42,2) = HCF(128,42) = HCF(298,128) = HCF(426,298) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 279 > 2, we apply the division lemma to 279 and 2, to get
279 = 2 x 139 + 1
Step 2: Since the reminder 2 ≠ 0, we apply division lemma to 1 and 2, 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 2 and 279 is 1
Notice that 1 = HCF(2,1) = HCF(279,2) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 654 > 1, we apply the division lemma to 654 and 1, to get
654 = 1 x 654 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 1, the HCF of 1 and 654 is 1
Notice that 1 = HCF(654,1) .
