Given numbers are 428, 757, 530, 847
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(428, 757) = 323996
GCD(428, 757) = ( 428 x 757 ) / 323996
= 428 / 757
= 428
Step2:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
Step3:
LCM(1, 847) = 847
GCD(1, 847) = ( 1 x 847 ) / 847
= 1 / 847
= 1
So, Greatest Common Divisor of 428, 757, 530, 847 is 1
