Given numbers are 521, 830, 472, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(521, 830) = 432430
GCD(521, 830) = ( 521 x 830 ) / 432430
= 521 / 830
= 521
Step2:
LCM(1, 472) = 472
GCD(1, 472) = ( 1 x 472 ) / 472
= 1 / 472
= 1
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 521, 830, 472, 428 is 1
