Given numbers are 530, 690, 162, 149
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(530, 690) = 36570
GCD(530, 690) = ( 530 x 690 ) / 36570
= 530 / 690
= 530
Step2:
LCM(10, 162) = 810
GCD(10, 162) = ( 10 x 162 ) / 810
= 10 / 162
= 10
Step3:
LCM(2, 149) = 298
GCD(2, 149) = ( 2 x 149 ) / 298
= 2 / 149
= 2
So, Greatest Common Divisor of 530, 690, 162, 149 is 1
