Given numbers are 100, 434, 970, 987
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(100, 434) = 21700
GCD(100, 434) = ( 100 x 434 ) / 21700
= 100 / 434
= 100
Step2:
LCM(2, 970) = 970
GCD(2, 970) = ( 2 x 970 ) / 970
= 2 / 970
= 2
Step3:
LCM(2, 987) = 1974
GCD(2, 987) = ( 2 x 987 ) / 1974
= 2 / 987
= 2
So, Greatest Common Divisor of 100, 434, 970, 987 is 1
