Given numbers are 105, 621, 757, 140
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(105, 621) = 21735
GCD(105, 621) = ( 105 x 621 ) / 21735
= 105 / 621
= 105
Step2:
LCM(3, 757) = 2271
GCD(3, 757) = ( 3 x 757 ) / 2271
= 3 / 757
= 3
Step3:
LCM(1, 140) = 140
GCD(1, 140) = ( 1 x 140 ) / 140
= 1 / 140
= 1
So, Greatest Common Divisor of 105, 621, 757, 140 is 1
