Given numbers are 198, 280, 964, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 280) = 27720
GCD(198, 280) = ( 198 x 280 ) / 27720
= 198 / 280
= 198
Step2:
LCM(2, 964) = 964
GCD(2, 964) = ( 2 x 964 ) / 964
= 2 / 964
= 2
Step3:
LCM(2, 621) = 1242
GCD(2, 621) = ( 2 x 621 ) / 1242
= 2 / 621
= 2
So, Greatest Common Divisor of 198, 280, 964, 621 is 1
