Given numbers are 343, 780, 450, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(343, 780) = 267540
GCD(343, 780) = ( 343 x 780 ) / 267540
= 343 / 780
= 343
Step2:
LCM(1, 450) = 450
GCD(1, 450) = ( 1 x 450 ) / 450
= 1 / 450
= 1
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 343, 780, 450, 956 is 1
