Given numbers are 651, 770, 324, 428
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(651, 770) = 71610
GCD(651, 770) = ( 651 x 770 ) / 71610
= 651 / 770
= 651
Step2:
LCM(7, 324) = 2268
GCD(7, 324) = ( 7 x 324 ) / 2268
= 7 / 324
= 7
Step3:
LCM(1, 428) = 428
GCD(1, 428) = ( 1 x 428 ) / 428
= 1 / 428
= 1
So, Greatest Common Divisor of 651, 770, 324, 428 is 1
