Given numbers are 690, 895, 209, 739
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 895) = 123510
GCD(690, 895) = ( 690 x 895 ) / 123510
= 690 / 895
= 690
Step2:
LCM(5, 209) = 1045
GCD(5, 209) = ( 5 x 209 ) / 1045
= 5 / 209
= 5
Step3:
LCM(1, 739) = 739
GCD(1, 739) = ( 1 x 739 ) / 739
= 1 / 739
= 1
So, Greatest Common Divisor of 690, 895, 209, 739 is 1
