Given numbers are 830, 216, 100, 805
The list of prime factors of all numbers are
Prime factors of 830 are 2 x 5 x 83
Prime factors of 216 are 2 x 2 x 2 x 3 x 3 x 3
Prime factors of 100 are 2 x 2 x 5 x 5
Prime factors of 805 are 5 x 7 x 23
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 830, 216, 100, 805
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 216) = 89640
GCD(830, 216) = ( 830 x 216 ) / 89640
= 830 / 216
= 830
Step2:
LCM(2, 100) = 100
GCD(2, 100) = ( 2 x 100 ) / 100
= 2 / 100
= 2
Step3:
LCM(2, 805) = 1610
GCD(2, 805) = ( 2 x 805 ) / 1610
= 2 / 805
= 2
So, Greatest Common Divisor of 830, 216, 100, 805 is 1
