Given numbers are 621, 666, 348, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(621, 666) = 45954
GCD(621, 666) = ( 621 x 666 ) / 45954
= 621 / 666
= 621
Step2:
LCM(9, 348) = 1044
GCD(9, 348) = ( 9 x 348 ) / 1044
= 9 / 348
= 9
Step3:
LCM(3, 530) = 1590
GCD(3, 530) = ( 3 x 530 ) / 1590
= 3 / 530
= 3
So, Greatest Common Divisor of 621, 666, 348, 530 is 1
