GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(690, 206) = 71070
GCD(690, 206) = ( 690 x 206 ) / 71070
= 690 / 206
= 690
Step2:
LCM(2, 530) = 530
GCD(2, 530) = ( 2 x 530 ) / 530
= 2 / 530
= 2
Step3:
LCM(2, 626) = 626
GCD(2, 626) = ( 2 x 626 ) / 626
= 2 / 626
= 2
So, Greatest Common Divisor of 690, 206, 530, 626 is 2
