Given numbers are 858, 147, 742, 530
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(858, 147) = 42042
GCD(858, 147) = ( 858 x 147 ) / 42042
= 858 / 147
= 858
Step2:
LCM(3, 742) = 2226
GCD(3, 742) = ( 3 x 742 ) / 2226
= 3 / 742
= 3
Step3:
LCM(1, 530) = 530
GCD(1, 530) = ( 1 x 530 ) / 530
= 1 / 530
= 1
So, Greatest Common Divisor of 858, 147, 742, 530 is 1
