GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(440, 820) = 18040
GCD(440, 820) = ( 440 x 820 ) / 18040
= 440 / 820
= 440
Step2:
LCM(20, 634) = 6340
GCD(20, 634) = ( 20 x 634 ) / 6340
= 20 / 634
= 20
Step3:
LCM(2, 152) = 152
GCD(2, 152) = ( 2 x 152 ) / 152
= 2 / 152
= 2
So, Greatest Common Divisor of 440, 820, 634, 152 is 2
