Given numbers are 715, 103, 978, 956
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(715, 103) = 73645
GCD(715, 103) = ( 715 x 103 ) / 73645
= 715 / 103
= 715
Step2:
LCM(1, 978) = 978
GCD(1, 978) = ( 1 x 978 ) / 978
= 1 / 978
= 1
Step3:
LCM(1, 956) = 956
GCD(1, 956) = ( 1 x 956 ) / 956
= 1 / 956
= 1
So, Greatest Common Divisor of 715, 103, 978, 956 is 1
