Given numbers are 343, 133, 155, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 133) = 6517
GCD(343, 133) = ( 343 x 133 ) / 6517
= 343 / 133
= 343
Step2:
LCM(7, 155) = 1085
GCD(7, 155) = ( 7 x 155 ) / 1085
= 7 / 155
= 7
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 343, 133, 155, 770 is 1
