Given numbers are 155, 205, 346, 142
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(155, 205) = 6355
GCD(155, 205) = ( 155 x 205 ) / 6355
= 155 / 205
= 155
Step2:
LCM(5, 346) = 1730
GCD(5, 346) = ( 5 x 346 ) / 1730
= 5 / 346
= 5
Step3:
LCM(1, 142) = 142
GCD(1, 142) = ( 1 x 142 ) / 142
= 1 / 142
= 1
So, Greatest Common Divisor of 155, 205, 346, 142 is 1
