Given numbers are 415, 346, 770, 915
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(415, 346) = 143590
GCD(415, 346) = ( 415 x 346 ) / 143590
= 415 / 346
= 415
Step2:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
Step3:
LCM(1, 915) = 915
GCD(1, 915) = ( 1 x 915 ) / 915
= 1 / 915
= 1
So, Greatest Common Divisor of 415, 346, 770, 915 is 1
