Given numbers are 742, 847, 879, 685
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(742, 847) = 89782
GCD(742, 847) = ( 742 x 847 ) / 89782
= 742 / 847
= 742
Step2:
LCM(7, 879) = 6153
GCD(7, 879) = ( 7 x 879 ) / 6153
= 7 / 879
= 7
Step3:
LCM(1, 685) = 685
GCD(1, 685) = ( 1 x 685 ) / 685
= 1 / 685
= 1
So, Greatest Common Divisor of 742, 847, 879, 685 is 1
