Given numbers are 964, 706, 385, 420
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(964, 706) = 340292
GCD(964, 706) = ( 964 x 706 ) / 340292
= 964 / 706
= 964
Step2:
LCM(2, 385) = 770
GCD(2, 385) = ( 2 x 385 ) / 770
= 2 / 385
= 2
Step3:
LCM(1, 420) = 420
GCD(1, 420) = ( 1 x 420 ) / 420
= 1 / 420
= 1
So, Greatest Common Divisor of 964, 706, 385, 420 is 1
