GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(830, 660) = 54780
GCD(830, 660) = ( 830 x 660 ) / 54780
= 830 / 660
= 830
Step2:
LCM(10, 392) = 1960
GCD(10, 392) = ( 10 x 392 ) / 1960
= 10 / 392
= 10
Step3:
LCM(2, 964) = 964
GCD(2, 964) = ( 2 x 964 ) / 964
= 2 / 964
= 2
So, Greatest Common Divisor of 830, 660, 392, 964 is 2
