GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(630, 780) = 16380
GCD(630, 780) = ( 630 x 780 ) / 16380
= 630 / 780
= 630
Step2:
LCM(30, 844) = 12660
GCD(30, 844) = ( 30 x 844 ) / 12660
= 30 / 844
= 30
Step3:
LCM(2, 758) = 758
GCD(2, 758) = ( 2 x 758 ) / 758
= 2 / 758
= 2
So, Greatest Common Divisor of 630, 780, 844, 758 is 2
