The list of prime factors of all numbers are
Prime factors of 210 are 2 x 3 x 5 x 7
Prime factors of 142 are 2 x 71
Prime factors of 520 are 2 x 2 x 2 x 5 x 13
Prime factors of 545 are 5 x 109
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 210, 142, 520, 545
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(210, 142) = 14910
GCD(210, 142) = ( 210 x 142 ) / 14910
= 210 / 142
= 210
Step2:
LCM(2, 520) = 520
GCD(2, 520) = ( 2 x 520 ) / 520
= 2 / 520
= 2
Step3:
LCM(2, 545) = 1090
GCD(2, 545) = ( 2 x 545 ) / 1090
= 2 / 545
= 2
So, Greatest Common Divisor of 210, 142, 520, 545 is 1
