Given numbers are 161, 722, 879, 690
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(161, 722) = 116242
GCD(161, 722) = ( 161 x 722 ) / 116242
= 161 / 722
= 161
Step2:
LCM(1, 879) = 879
GCD(1, 879) = ( 1 x 879 ) / 879
= 1 / 879
= 1
Step3:
LCM(1, 690) = 690
GCD(1, 690) = ( 1 x 690 ) / 690
= 1 / 690
= 1
So, Greatest Common Divisor of 161, 722, 879, 690 is 1
