Given numbers are 488, 608, 247, 820
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(488, 608) = 37088
GCD(488, 608) = ( 488 x 608 ) / 37088
= 488 / 608
= 488
Step2:
LCM(8, 247) = 1976
GCD(8, 247) = ( 8 x 247 ) / 1976
= 8 / 247
= 8
Step3:
LCM(1, 820) = 820
GCD(1, 820) = ( 1 x 820 ) / 820
= 1 / 820
= 1
So, Greatest Common Divisor of 488, 608, 247, 820 is 1
