Steps to Calculate GCD of 98, 87, 38, 84 using LCM Formula
Given numbers are 98, 87, 38, 84
GCD of 2 numbers formula is GCD(a, b) = ( a x b) / LCM(a, b)
Apply this formula for all numbers.
Step1:
LCM(98, 87) = 8526
GCD(98, 87) = ( 98 x 87 ) / 8526
= 98 / 87
= 98
Step2:
LCM(1, 38) = 38
GCD(1, 38) = ( 1 x 38 ) / 38
= 1 / 38
= 1
Step3:
LCM(1, 84) = 84
GCD(1, 84) = ( 1 x 84 ) / 84
= 1 / 84
= 1
So, Greatest Common Divisor of 98, 87, 38, 84 is 1
