GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 430) = 29670
GCD(690, 430) = ( 690 x 430 ) / 29670
= 690 / 430
= 690
Step2:
LCM(10, 968) = 4840
GCD(10, 968) = ( 10 x 968 ) / 4840
= 10 / 968
= 10
Step3:
LCM(2, 867) = 1734
GCD(2, 867) = ( 2 x 867 ) / 1734
= 2 / 867
= 2
So, Greatest Common Divisor of 690, 430, 968, 867 is 1
