Given numbers are 820, 157, 815, 543
The list of prime factors of all numbers are
Prime factors of 820 are 2 x 2 x 5 x 41
Prime factors of 157 are 157
Prime factors of 815 are 5 x 163
Prime factors of 543 are 3 x 181
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 820, 157, 815, 543
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(820, 157) = 128740
GCD(820, 157) = ( 820 x 157 ) / 128740
= 820 / 157
= 820
Step2:
LCM(1, 815) = 815
GCD(1, 815) = ( 1 x 815 ) / 815
= 1 / 815
= 1
Step3:
LCM(1, 543) = 543
GCD(1, 543) = ( 1 x 543 ) / 543
= 1 / 543
= 1
So, Greatest Common Divisor of 820, 157, 815, 543 is 1
