GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(668, 763) = 509684
GCD(668, 763) = ( 668 x 763 ) / 509684
= 668 / 763
= 668
Step2:
LCM(1, 960) = 960
GCD(1, 960) = ( 1 x 960 ) / 960
= 1 / 960
= 1
Step3:
LCM(1, 855) = 855
GCD(1, 855) = ( 1 x 855 ) / 855
= 1 / 855
= 1
So, Greatest Common Divisor of 668, 763, 960, 855 is 1
