The list of prime factors of all numbers are
Prime factors of 415 are 5 x 83
Prime factors of 840 are 2 x 2 x 2 x 3 x 5 x 7
Prime factors of 340 are 2 x 2 x 5 x 17
Prime factors of 141 are 3 x 47
The above numbers do not have any common prime factor. So GCD is 1
Given numbers are 415, 840, 340, 141
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 840) = 69720
GCD(415, 840) = ( 415 x 840 ) / 69720
= 415 / 840
= 415
Step2:
LCM(5, 340) = 340
GCD(5, 340) = ( 5 x 340 ) / 340
= 5 / 340
= 5
Step3:
LCM(5, 141) = 705
GCD(5, 141) = ( 5 x 141 ) / 705
= 5 / 141
= 5
So, Greatest Common Divisor of 415, 840, 340, 141 is 1
