Given numbers are 198, 487, 474, 770
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(198, 487) = 96426
GCD(198, 487) = ( 198 x 487 ) / 96426
= 198 / 487
= 198
Step2:
LCM(1, 474) = 474
GCD(1, 474) = ( 1 x 474 ) / 474
= 1 / 474
= 1
Step3:
LCM(1, 770) = 770
GCD(1, 770) = ( 1 x 770 ) / 770
= 1 / 770
= 1
So, Greatest Common Divisor of 198, 487, 474, 770 is 1
