Given numbers are 836, 248, 515, 621
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(836, 248) = 51832
GCD(836, 248) = ( 836 x 248 ) / 51832
= 836 / 248
= 836
Step2:
LCM(4, 515) = 2060
GCD(4, 515) = ( 4 x 515 ) / 2060
= 4 / 515
= 4
Step3:
LCM(1, 621) = 621
GCD(1, 621) = ( 1 x 621 ) / 621
= 1 / 621
= 1
So, Greatest Common Divisor of 836, 248, 515, 621 is 1
