HCF Calculator using the Euclid Division Algorithm helps you to find the Highest common factor (HCF) easily for 602, 728, 90 i.e. 2 the largest integer that leaves a remainder zero for all numbers.
HCF of 602, 728, 90 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 602, 728, 90 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 602, 728, 90 is 2.
HCF(602, 728, 90) = 2
HCF of 602, 728, 90 using Euclid's algorithm
Highest common factor or Highest common divisor (hcd) can be calculated by Euclid's algotithm.
Highest common factor (HCF) of 602, 728, 90 is 2.
Highest Common Factor of 602,728,90 is 2
Step 1: Since 728 > 602, we apply the division lemma to 728 and 602, to get
728 = 602 x 1 + 126
Step 2: Since the reminder 602 ≠ 0, we apply division lemma to 126 and 602, to get
602 = 126 x 4 + 98
Step 3: We consider the new divisor 126 and the new remainder 98, and apply the division lemma to get
126 = 98 x 1 + 28
We consider the new divisor 98 and the new remainder 28,and apply the division lemma to get
98 = 28 x 3 + 14
We consider the new divisor 28 and the new remainder 14,and apply the division lemma to get
28 = 14 x 2 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 14, the HCF of 602 and 728 is 14
Notice that 14 = HCF(28,14) = HCF(98,28) = HCF(126,98) = HCF(602,126) = HCF(728,602) .
We can take hcf of as 1st numbers and next number as another number to apply in Euclidean lemma
Step 1: Since 90 > 14, we apply the division lemma to 90 and 14, to get
90 = 14 x 6 + 6
Step 2: Since the reminder 14 ≠ 0, we apply division lemma to 6 and 14, to get
14 = 6 x 2 + 2
Step 3: We consider the new divisor 6 and the new remainder 2, and apply the division lemma to get
6 = 2 x 3 + 0
The remainder has now become zero, so our procedure stops. Since the divisor at this stage is 2, the HCF of 14 and 90 is 2
Notice that 2 = HCF(6,2) = HCF(14,6) = HCF(90,14) .
