Given numbers are 612, 648, 858, 991
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(612, 648) = 11016
GCD(612, 648) = ( 612 x 648 ) / 11016
= 612 / 648
= 612
Step2:
LCM(36, 858) = 5148
GCD(36, 858) = ( 36 x 858 ) / 5148
= 36 / 858
= 36
Step3:
LCM(6, 991) = 5946
GCD(6, 991) = ( 6 x 991 ) / 5946
= 6 / 991
= 6
So, Greatest Common Divisor of 612, 648, 858, 991 is 1
